Due to the 1.3s exposure time, no individual dust particles can be seen. Dust particles are present in the air, but not in the crystal. In the crystal, some part of the blue light is absorbed and re-emitted as orange light, which is called fluorescence. Most of the blue light just continues to the other end of the crystal.\n\u003C\u002Fp>\nOn the lower left you can see the laser beam going in. Part of the light is reflected on the front surface of the crystal; this is the beam you see on the upper left. In the crystal, the two polarisations are refracted by different angles, forming two beams in the crystal. At the end surface, the two beams (both of which are polarised along the axes of the crystal) are refracted back to their original direction, forming the two parallel beams on the right. Inside the crystal, the two beams cause fluorescence and non-polarised orange light is emitted from each point along both beams in every direction. As this light leaves the crystal, it's separated into two orthogonal polarisations, which are refracted by different angles, so that the observer sees four orange beams. The additional spots and beams you can see result from internal reflections.","Jan Pavelka",3456,2304,{"id":1437,"source_url":1438,"license_code":1439,"credit_html":1440,"title":7,"description":11,"author":11,"original_width":1441,"original_height":1442},29343,"https:\u002F\u002Fgeocollections.info\u002Ffile\u002F55490","CC BY 4.0","Photo: Unknown author — http:\u002F\u002Fcreativecommons.org\u002Flicenses\u002Fby\u002F4.0\u002F, courtesy of \u003Ca href=\"https:\u002F\u002Fgeocollections.info\u002Ffile\u002F55490\" rel=\"noopener\">Department of Geology, TalTech\u003C\u002Fa> via Europeana",1000,747,{"id":1444,"source_url":1445,"license_code":1429,"credit_html":1446,"title":7,"description":11,"author":11,"original_width":1441,"original_height":1447},29344,"https:\u002F\u002Fgeocollections.info\u002Ffile\u002F129493","Photo: Unknown author — http:\u002F\u002Fcreativecommons.org\u002Flicenses\u002Fby-sa\u002F4.0\u002F, courtesy of \u003Ca href=\"https:\u002F\u002Fgeocollections.info\u002Ffile\u002F129493\" rel=\"noopener\">University of Tartu, Natural History Museum\u003C\u002Fa> via Europeana",903,{"id":1449,"source_url":1450,"license_code":1419,"credit_html":1451,"title":1452,"description":1453,"author":1454,"original_width":1455,"original_height":1456},37895,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=10030057","Robert M.

One so rarely sees parisite on crystallized matrix from any locality, and the contrast to these calcites really addds a lot, visually, to the desirability of the piece. Parisite today comes from both France and Malawi, and especially Zagi Mountain in Pakistan, in excellent crystals. But, they are all of markedly different habit from these classic, and oldest good examples of the species from Muzo. Believe it or not, Muzo was actually the type locality back in the early 1900s, in fact! Other locales known today produce gemmier or bigger examples, but for the overall combination of qualities you would want most, and for good matrix, this locality is still the most desirable. I have handled several over the years of some stature form here, and among them I find this one ranks highly.

At its simplest, a mineral is a naturally-occurring solid chemical.  Currently, there are over 6000 named and described minerals - about 200 of them are common and about 20 of them are very common.  Mineral classification is based on anion chemistry.  Major categories of minerals are: elements, sulfides, oxides, halides, carbonates, sulfates, phosphates, and silicates.\n\u003C\u002Fp>\u003Cp>The sulfide minerals contain one or more sulfide anions (S-2).  The sulfides are usually considered together with the arsenide minerals, the sulfarsenide minerals, and the telluride minerals.  Many sulfides are economically significant, as they occur commonly in ores.  The metals that combine with S-2 are mainly Fe, Cu, Ni, Ag, etc.  Most sulfides have a metallic luster, are moderately soft, and are noticeably heavy for their size.  These minerals will not form in the presence of free oxygen.  Under an oxygen-rich atmosphere, sulfide minerals tend to chemically weather to various oxide and hydroxide minerals.\n\u003C\u002Fp>\u003Cp>Chalcocite is a significant copper ore mineral having the formula Cu2S - copper sulfide.  It has a metallic luster, a dark gray to black color and streak, no obvious cleavage, is moderately heavy for its size, and is moderately soft (H = 2.5 to 3).  Chalcocite is found with other copper minerals such as chalcopyrite.  It usually forms in the near-surface, secondary enrichment zone at and below the water table, in areas having copper mineralization.  It also occurs as a primary mineral in some hydrothermal veins.\n\u003C\u002Fp>\u003Cp>The specimen seen here is from northern Michigan's White Pine Mine and was hosted by the Nonesuch Formation, a 1.07 to 1.08 billion years old, nonmarine, mixed siliciclastics unit.

(public display, Minnesota Discovery Center, Chisholm, Minnesota, USA)\n\u003C\u002Fp>\u003Cp>A mineral is a naturally-occurring, solid, inorganic, crystalline substance having a fairly definite chemical composition and having fairly definite physical properties.  At its simplest, a mineral is a naturally-occurring solid chemical.  Currently, there are over 5400 named and described minerals - about 200 of them are common and about 20 of them are very common.  Mineral classification is based on anion chemistry.  Major categories of minerals are: elements, sulfides, oxides, halides, carbonates, sulfates, phosphates, and silicates.\n\u003C\u002Fp>\u003Cp>The carbonate minerals all contain one or more carbonate (CO3-2) anions.\n\u003C\u002Fp>\u003Cp>Aragonite has the same chemistry as calcite - it is calcium carbonate (CaCO3).  Why is it a different mineral?  Aragonite has a different molecular structure - the atoms are packed differently.  Different minerals having the same chemical formula are called polymorphs (another good example is graphite & diamond - both C).\n\u003C\u002Fp>\u003Cp>The difference in atomic-level packing between calcite and aragonite can be seen at the level of mineral hand samples.  Aragonite forms crystals in the orthorhombic class.  Many aragonite crystals are acicular (needle-like).  Many aragonites form pseudohexagonal crystals, the result of 6 orthorhombic prisms growing parallel to each other.\n\u003C\u002Fp>\u003Cp>Like calcite, aragonite is moderately soft (H=3), is often clearish to whitish to yellowish, and easily bubbles in acid.  Aragonite is a little bit heavier than calcite, due to closer packing of atoms.\n\u003C\u002Fp>\u003Cp>Most modern seashells & coral skeletons are composed of the aragonite.  Whitish-colored lime sand beaches in the world are aragonitic.  Occasionally, \"whitings\" are seen in shallow, warm ocean environments.  Whitings (cloudy, milky seawater) turn out to be loaded with tiny hair-like needles of aragonite.\n\u003C\u002Fp>\u003Cp>In the rock record, aragonitic or aragonite-rich sediments convert to calcite over time.  Cenozoic-aged carbonate sedimentary rocks are often aragonitic.  Mesozoic- and Paleozoic-aged carbonates are almost always calcitic.  Many ancient fossils have had their aragonitic shells dissolved away.  Ancient shells that were originally calcitic are often still well preserved.\n\u003C\u002Fp>\u003Cp>The sample shown above is a \"variety\" of aragonite called erzbergite, which is actually interlayered aragonite and calcite.

Perched along one side is a classic 7 cm peach-colored Stilbite bowtie, with one side-crystal attached for added drama. On top of the stalactite are two beautiful pink Heulandite fans, the largest of which is 4 cm long. And if all this wasn�t enough, the Heulandites and Stilbites are covered with a druse of sparkling Apophyllite crystals, which make the crystals appear as if they were covered by the pristine snow of Vermont.

At its simplest, a mineral is a naturally-occurring solid chemical.  Currently, there are over 5200 named and described minerals - about 200 of them are common and about 20 of them are very common.  Mineral classification is based on anion chemistry.  Major categories of minerals are: elements, sulfides, oxides, halides, carbonates, sulfates, phosphates, and silicates.\n\u003C\u002Fp>\u003Cp>The carbonate minerals all contain one or more carbonate (CO3-2) anions.\n\u003C\u002Fp>\u003Cp>Witherite is an uncommon barium carbonate mineral, BaCO3.  It has a nonmetallic, glassy to dull luster, varies in color from clear to white to grayish to yellowish to brownish to greenish, has a white streak, a hardness of 3 to 3.5, and is fairly heavy for its size.  Witherite readily bubbles in acid, as do many carbonate minerals.  Witherite forms transparent to translucent, columnar-shaped to prism-shaped orthorhombic crystals.  These crystals always grow parallel to each other, resulting in pseudohexagonal crystal forms.  Witherite does have cleavage, but the twinned nature of witherite crystals prevents easy examination of cleavage planes.  Other witherites are massive or granular or fibrous or botryoidal.  Perpendicular to the long axis of the pseudohexagonal crystals are obvious striations.\n\u003C\u002Fp>\u003Cp>Witherite is a minor ore mineral of barium (the dominant source of Ba is the barium sulfate mineral barite).  Witherite is typically found in some low-temperature hydrothermal veins.\n\u003C\u002Fp>\u003Cp>The witherite-calcite specimen shown here is from a Mississippi Valley-type deposit in southern Illinois.  Commonly abbreviated \"MVT\", Mississippi Valley-type deposits are named for a series of mineral deposits that occur in non-deformed platform sedimentary rocks along the Upper Mississippi River Valley, USA.  Many specific minerals occur in MVT deposits, but are dominated by galena, sphalerite, barite, and fluorite.  These minerals occur in caves and karst, paleokarst structures, in collapse fabrics, in pull-apart structures, etc.  MVT deposits in America are mined as important, large sources of lead ore and zinc ore.  The classic areas for MVT deposits are southern Illinois, the tristate area of Oklahoma-Missouri-Kansas, northern Kentucky, southwestern Wisconsin, and southeastern Missouri.  The minerals are hydrothermal in origin and were precipitated from basinal brines that were flushed out to the edges of large sedimentary basins (e.g., the Illinois Basin and the Black Warrior Basin).  In basin edge areas, the brines came into contact with Mississippian-aged carbonate rocks (limestone and dolostone), which caused mineralization.  The brines were 15% to 25% salinity with temperatures of 50 to 200 degrees Celsius (commonly 100 to 150 degrees C).  MVT mineralization usually occurs in limestone and dolostone but can also be hosted in shales, siltstones, sandstones, and conglomerates.  Gangue minerals include pyrite, marcasite, calcite, aragonite, dolomite, siderite, and quartz.  Up to 40 or 50 pulses of brine fluids are recorded in banding of mineral suites in MVT deposits (for example, sphalerite coatings in veins have a stratigraphy - each layer represents a pulse event).  Each pulse of water was probably expelled rapidly - overpressurization and friction likely caused the water to heat up.  Some bitumen (crystallized organic matter) can occur, which is an indication of the basinal origin of the brines.  The presence of asphalt-bitumen indicates some hydrocarbon migration occurred.  Some petroleum inclusions are found within fluorite crystals and petroleum scum occurs on fluorite crystals.  MVT deposits are associated with oil fields and the temperature of mineral precipitation matches the petroleum window.  The brines may simply have accompanied hydrocarbon fluids as they migrated updip.\n\u003C\u002Fp>\u003Cp>The high temperatures of these basin periphery deposits wasn't necessarily influenced by igneous hydrothermal activity.  Hot fluids can occur in basins that are deep enough for the geothermal gradient to be ~100 to 150 degrees Celsius.  If a permeable conduit horizon is present in a succession of interbedded siliciclastic sedimentary rocks, migration of hot, deep basinal brines may be quick enough to get MVT deposit conditions at basin margins.\n\u003C\u002Fp>\u003Cp>MVT deposits occur in the Upper Mississippi Valley of America as well as in northern Africa, Scandinavia, northwestern Canada, at scattered sites in Europe, and at some sites in the American Cordillera.  Some of these occurrences are in deformed host rocks.  MVT deposits have little to no precious metals - maybe a little copper (Cu).  Mineralization is usually associated with limestone or dolostone in fracture fillings and vugs.  Little host rock alteration has occurred - usually only dolomitization of limestones.\n\u003C\u002Fp>\u003Cp>The age of the host rocks in the Mississippi Valley area varies - it ranges from Cambrian to Mississippian.  Dating of mineralization has been difficult, but published ages indicate a near-latest Paleozoic to Mesozoic timing.\n\u003C\u002Fp>\u003Cp>MVT deposits in the Upper Mississippi River area are often divided into three subtypes based on the dominant mineral: 1) lead-rich (galena dominated); 2) zinc-rich (sphalerite dominated); and 3) fluorite-rich.\n\u003C\u002Fp>\u003Cp>This mineral specimen is from the Illinois-Kentucky Fluorspar District (\"fluorspar\" is a very old name for fluorite), which is an MVT fluoritic subtype.  Fluorite and fluorite-rich rocks are mined for the fluorine, which is principally used by the chemical industry to make HF - hydrofluoric acid.  Fluorite mineralization in this district occurred at about 277 Ma, during the Early Permian, according to one published study (Chesley et al., 1994).  Another study concluded that fluorite mineralization was much later, during the Late Jurassic (see Symons, 1994).\n\u003C\u002Fp>\u003Cp>Locality: Bethel Level of the Minerva Mine # 1, near the town of Cave-in-Rock, Illinois, USA\n\u003C\u002Fp>\n\u003Chr>\n\u003Cp>Photo gallery of witherite:\n<a href=\"\u003Ca rel=\"nofollow\" class=\"external free\" href=\"https:\u002F\u002Fwww.mindat.org\u002Fgallery.php?min=4299\">https:\u002F\u002Fwww.mindat.org\u002Fgallery.php?min=4299\u003C\u002Fa>\" rel=\"nofollow\">www.mindat.org\u002Fgallery.php?min=4299<\u002Fa>\n\u003C\u002Fp>\n\u003Chr>\n\u003Cp>Some info. on Mississippi Valley-type deposits was synthesized from:\n\u003C\u002Fp>\u003Cp>Chesley et al.

(each specimen is 3.2 cm across)\n\u003Cp>A mineral is a naturally-occurring, solid, inorganic, crystalline substance having a fairly definite chemical composition and having fairly definite physical properties.  At its simplest, a mineral is a naturally-occurring solid chemical.  Currently, there are over 5400 named and described minerals - about 200 of them are common and about 20 of them are very common.  Mineral classification is based on anion chemistry.  Major categories of minerals are: elements, sulfides, oxides, halides, carbonates, sulfates, phosphates, and silicates.\n\u003C\u002Fp>\u003Cp>The carbonate minerals all contain one or more carbonate (CO3-2) anions.\n\u003C\u002Fp>\u003Cp>Calcite is a common mineral.  It is calcium carbonate (CaCO3).  It has a nonmetallic luster, commonly clearish to whitish to yellowish to grayish in color, is moderately soft (H≡3), moderately light-weight, has hexagonal crystals, and rhombohedral cleavage (three cleavage planes at 75º & 105º angles - cleavage pieces look like lopsided boxes - see examples above).  The easiest way to identify calcite is to drop acid on it - it easily bubbles (effervesces) in acid.  The bubbles are carbon dioxide gas.  If the acid is dilute hydrochloric acid, the chemical reaction is:\n\u003C\u002Fp>\u003Cp>2HCl(aq) + CaCO3(s) -->> CO2(g)↑ + H2O(l) + CaCl2(aq)\n\u003C\u002Fp>\u003Cp>The most important & voluminous calcitic rocks in the world are limestone (sedimentary), marble (metamorphic), carbonatite (igneous), and travertine (speleothem, or \"cave formations\", and many hotspring deposits).

However, this is one of a relatively few examples I have seen of light pink rhodochrosite. This is very rare! And, a shell of such size is also very rare for the locality - to have crysatllized rhodo within is quite nice but the final notch in its fame is that the rhodochrosite is surrounded by a pretty layer of massive golden calcite which fille din the majority of the mass of the original shell, leaving a hole inside for the rhodo to line. The calcite is slightly buffed, I would think, to give it a smooth surface as you see it has (as if it were a geode half).

(14.2 cm across at its widest)\n\u003C\u002Fp>\u003Cp>A mineral is a naturally-occurring, solid, inorganic, crystalline substance having a fairly definite chemical composition and having fairly definite physical properties.  At its simplest, a mineral is a naturally-occurring solid chemical.  Currently, there are over 4900 named and described minerals - about 200 of them are common and about 20 of them are very common.  Mineral classification is based on anion chemistry.  Major categories of minerals are: elements, sulfides, oxides, halides, carbonates, sulfates, phosphates, and silicates.\n\u003C\u002Fp>\u003Cp>The sulfide minerals contain one or more sulfide anions (S-2).  The sulfides are usually considered together with the arsenide minerals, the sulfarsenide minerals, and the telluride minerals.  Many sulfides are economically significant, as they occur commonly in ores.  The metals that combine with S-2 are mainly Fe, Cu, Ni, Ag, etc.  Most sulfides have a metallic luster, are moderately soft, and are noticeably heavy for their size.  These minerals will not form in the presence of free oxygen.  Under an oxygen-rich atmosphere, sulfide minerals tend to chemically weather to various oxide and hydroxide minerals.\n\u003C\u002Fp>\u003Cp>Realgar and orpiment are both arsenic sulfides.  Realgar is an intensely reddish-orangish arsenic sulfide (AsS), while orpiment is a bright yellow-colored arsenic sulfide (As2S3).  They are always associated with each other.  Arsenic is a rare element in Earth’s crust, but because As has very few uses in modern society, it has practically no value.  Orpiment & realgar have a nonmetallic luster and are fairly soft (H=1 for yellow orpiment & H=2 for reddish-orange realgar).  The two minerals are fairly insoluble, but they do volatilize readily.  When heated, they release a garlic smell (arsenic).  Realgar tends to alter to orpiment when exposed at Earth's surface.\n\u003C\u002Fp>\u003Cp>One of the prettiest rocks I’ve ever seen is this specimen from the Getchell Mine of northern Nevada, USA.  The rock itself (gray portion) is marble.  The large whitish gray crystals at right and right-center and top are calcite (CaCO3 - calcium carbonate).  The red crystals are realgar (AsS; a.k.a. As4S4 - arsenic sulfide).  The yellowish and orangish areas are pararealgar, which has the same chemical formula as realgar.

(field of view ~3.5 cm across)\n\u003C\u002Fp>\u003Cp>A mineral is a naturally-occurring, solid, inorganic, crystalline substance having a fairly definite chemical composition and having fairly definite physical properties.  At its simplest, a mineral is a naturally-occurring solid chemical.  Currently, there are over 4900 named and described minerals - about 200 of them are common and about 20 of them are very common.  Mineral classification is based on anion chemistry.  Major categories of minerals are: elements, sulfides, oxides, halides, carbonates, sulfates, phosphates, and silicates.\n\u003C\u002Fp>\u003Cp>The sulfide minerals contain one or more sulfide anions (S-2).  The sulfides are usually considered together with the arsenide minerals, the sulfarsenide minerals, and the telluride minerals.  Many sulfides are economically significant, as they occur commonly in ores.  The metals that combine with S-2 are mainly Fe, Cu, Ni, Ag, etc.  Most sulfides have a metallic luster, are moderately soft, and are noticeably heavy for their size.  These minerals will not form in the presence of free oxygen.  Under an oxygen-rich atmosphere, sulfide minerals tend to chemically weather to various oxide and hydroxide minerals.\n\u003C\u002Fp>\u003Cp>Realgar and orpiment are both arsenic sulfides.  Realgar is an intensely reddish-orangish arsenic sulfide (AsS), while orpiment is a bright yellow-colored arsenic sulfide (As2S3).  They are always associated with each other.  Arsenic is a rare element in Earth’s crust, but because As has very few uses in modern society, it has practically no value.  Orpiment & realgar have a nonmetallic luster and are fairly soft (H=1 for yellow orpiment & H=2 for reddish-orange realgar).  The two minerals are fairly insoluble, but they do volatilize readily.  When heated, they release a garlic smell (arsenic).  Realgar tends to alter to orpiment when exposed at Earth's surface.\n\u003C\u002Fp>\u003Cp>One of the prettiest specimens I’ve ever seen is this specimen from the Getchell Mine of northern Nevada, USA.  The whitish gray crystals are calcite (CaCO3 - calcium carbonate).  The red crystals are realgar (AsS; a.k.a. As4S4 - arsenic sulfide).  The small specks of yellowish and orangish areas are pararealgar, which has the same chemical formula as realgar.  Realgar is unstable when exposed to light, so the orangish-yellowish pararealgar you see in this specimen used to be red realgar.\n\u003C\u002Fp>\u003Cp>Geology - Cambrian-aged Preble Formation limestone, contact metamorphosed into marble by the Cretaceous-aged Osgood Granodiorite Stock.  During the late Middle Eocene, at 39 million years ago, the rock was subjected to Carlin-type mineralization by fluids moving along the Getchell Fault (a major normal fault formed during Basin & Range extensional tectonics).

I made some fumbling comment about how I could not sell Swiss hematites in the US so well, but I thought the calcite so neat and unusual, like dhte contrast, and well...my source got me. Apparently the piece turned up at a small show, having come directly from a miner in Mexico up to the show and missing the normal channels such major pieces often get funnelled into. The calcite is a wonderful accent, and I cannot ever recall seeing another Mexican specimen of polybasite with such sheer , amazing contrast. Visually, this leaps out. The sparkling drusy calcite highlights the metallic, lustrous blades so nicely. Small barrel-like stephanites are in association as well (on the back), according to Dr. Terry Wallace who examined the specimen for me at the Denver show. He confirmed for me that the piece came from this small shaft adjoining two slightly different deposits, an aberration which is the reason why you have the calcite and the polybasite in the same place at the same time...normally not seen. This is an important Mexican specimen, and an important silver species specimen. If i can presume, I will say that 10 years ago it would have been quickly sold into the Miguel Romero collection at any price, and fit right in with his museum-level Mexican silver species suite which I have recently acuired fom the University of Arizona Science Center .\u003C\u002Fdd>\u003C\u002Fdl>\u003C\u002Fdd>\u003C\u002Fdl>",{"id":4137,"source_url":4138,"license_code":1419,"credit_html":4139,"title":4140,"description":4135,"author":1454,"original_width":1514,"original_height":4141},74842,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=10447151","Robert M.

The easiest way to identify calcite is to drop acid on it - it easily bubbles (effervesces) in acid.  The bubbles are carbon dioxide gas.  If the acid is dilute hydrochloric acid, the chemical reaction is:\n\u003C\u002Fp>\u003Cp>2HCl(aq) + CaCO3(s) -->> CO2(g)↑ + H2O(l) + CaCl2(aq)\n\u003C\u002Fp>\u003Cp>The most important & voluminous calcitic rocks in the world are limestone (sedimentary), marble (metamorphic), carbonatite (igneous), and travertine (speleothem, or \"cave formations\", and many hotspring deposits).

Egyptians carved calcite into vessels, statues, and ritual objects, and associated the stone with the goddess Bast. Her name lives on in *alabaster*, the term still used for the finely banded calcite that Egyptian artisans worked[1].\n\nIn 79 CE, Pliny the Elder gave the mineral its first written name in Latin: *calx*, meaning *lime*[2]. The word survives in modern technical vocabulary as a doublet of *chalk*[3].\n\nIn Viking-era Scandinavia, a rhombohedral cleavage piece of calcite may have been the *sunstone* the *Icelandic Sagas* describe as a navigation aid[4].\n\nIn 1669, the Danish scientist Rasmus Bartholin first described an optical curiosity of calcite[5]. Held against a written page, a clear cleavage rhomb produces a double image — the effect now called birefringence. The clearest specimens, then known as *Iceland spar*, became the textbook material for studying the effect.\n\nBy the 19th century, German mineralogical writing had settled on *Calcit*[6]. English borrowed it as *calcite* — the *-ite* suffix is the standard for mineral names.","claude-opus-4-7","1.7.0","2026-06-01 14:23:45",{"markdown":5016,"model_version":5012,"prompt_version":5013,"reviewed_at":5017},"Calcite is the rock that most of modern civilisation is built from. Burned, it becomes lime — the binding agent in the cement that fixes concrete and mortar[1]. Quarried in bulk, it becomes limestone and marble, used as building stone and as crushed aggregate[2].\n\nIn farming, ground limestone — *agricultural lime* — is spread across fields to raise soil pH and supply calcium to crops[3].\n\nClear cleavage rhombs of optical-grade calcite — historically known as Iceland spar — go into optical equipment for microscopes and laboratory instruments[4].\n\nIndustrially synthesised *precipitated calcium carbonate*, made by reprecipitating ground calcite, is mainly used as a filler and coating in the paper industry[5]. The same chemistry now extends to *microbially induced calcite precipitation* — used in soil remediation, soil stabilization, and concrete repair[6].","2026-06-01 14:28:09"]
