The cuboctahedron (combined cube and octahedron) is less common than the combination of a cube and a docecahedron, the cubododecahedron. \r\nThe faces of some crystal forms are more easily etched by nature than other faces, although this also depends on other parameters, and so none of the forms will always be smooth. Not all crystal faces will always be present, and sometimes certain faces are more developed than others, even within the same crystal form. Consequently, elongated crystals of fluorite have been observed.\r\n\r\nCrystals distorted at times by unequal development of faces, as of {013}.

Precious metal mineralization occurs in the Cripple Creek Diatreme, the root zone of a deeply eroded volcano dating to the Early Oligocene (32 Ma).  The dominant lithology at Cripple Creek is phonolite, a scarce, alkaline, intermediate, extrusive igneous rock.  Cripple Creek gold can be found in its native state (Au), but it typically occurs in the form of gold telluride minerals: for example, calaverite - AuTe2, sylvanite - (Au,Ag)2Te4, petzite - Ag3AuTe2, krennerite - (Au,Ag)Te2, and nagyagite - Pb5Au(Sb,Bi)Te2S6).  Silver also occurs in some Cripple Creek minerals, including sylvanite, petzite, krennerite, hessite - Ag2Te, tennantite - (Cu,Ag,Fe,Zn)12As4S13, acanthite - Ag2S, and argentian tetrahedrite - (Cu,Fe,Ag,Zn)12Sb4S13.\n\u003C\u002Fp>\u003Cp>Seen here is a purple fluorite vein at the Cresson Pit.  Precious metal tellurides are often intimately mixed with fluorite in these thin veins.  They were the targets of historic subsurface mine tunnels.\n\u003C\u002Fp>\n\u003Chr>\n\u003Cp>The following are my personal notes from a 2007 presentation on Cripple Creek geology by mine representative Tim Brown:\n\u003C\u002Fp>\u003Cp>The Cripple Creek District has four different pits being mined now, including the main Cresson Pit.  The Cripple Creek & Victor Gold Mining Company is an AngloGold Ashanti joint venture operation.  The heart of the mining district is a 32 Ma diatreme.  It erupted along a major structural feature - through deep cracks in a big shear zone along a syenite-augen gneiss contact.\nSome Precambrian rocks occur in the diatreme.\nThere are three eruptive sub-basins to this diatreme - one in the north, one in the south, and one in the southwest.  The diatreme consists of volcanic breccias and phonolites and lamprophyre breccias.  The lamprophyre breccia is relatively small, but the margins have produced 2.5 million ounces of gold.\n\u003C\u002Fp>\u003Cp>Types of gold mineralization in the Cripple Creek District:\n1) Lamprophyre breccia-hosted gold mineralization - 2.5 million ounces of gold (Cresson Mine).\n2) Au-Te rich, sheeted vein system - 4.3 million ounces of gold (Portland-Independence Mine).\n3) Au-hydrothermal breccias\n\u003C\u002Fp>\u003Cp>Most Cripple Creek rocks are phonolites (earlier intrusions) and trachytes.  All are on the alkaline side of extrusive rock classification.  Later intrusions are mafic.  Finally, there are ultramafic lamprophyres.\n\u003C\u002Fp>\u003Cp>When gold is poured here, ~30% of each button is silver.\n\u003C\u002Fp>\u003Cp>The Cripple Creek diatreme is 4.3 miles in size, in an east-west direction, and 4 miles across in a north-south direction.  Some of the old underground workings along the gold telluride vein systems reached down to 3000’ depth.\n\u003C\u002Fp>\u003Cp>Structural features in the diatreme are probably related to the Rio Grande Rift.\nThis was an active volcano at one time.\nThere are lots of north-south trending veins & northeast-southwest trending veins here.\nThe district was discovered in 1891.  It’s been producing gold for 110 years.\nGeochemistry of altered & mineralized rocks in the Cripple Creek District - can see a characteristic enrichment of a certain suite of elements (Au, Te, Ag, Sb, W), especially gold.  A similar pattern is seen in alkaline districts elsewhere.  Ca, Na, Cs were systematically depleted.  Mo is systematically enriched in all the mineralized zones.  Other base metals have an erratic enrichment-depletion pattern.\nHigh-grade gold ore rocks here are always associated with potassic alteration.  But not all K-altered rocks have high-grade gold ore.\nThere are NE trends, E-W trends, N-S trends, and NW trends in the Cripple Creek area.  On a resistivity map, can readily see the Cripple Creek Diatreme boundary.\nCan also readily see the diatreme outline on a magnetic signature map, plus the syenite-augen gneiss boundary, trending northeast.\nGravity maps show ENE trends and a strong N-S trend (gravity low), which extends under Precambrian rocks at the surface.\nCurrently, gold mining at Cripple Creek is in surface pits.  They may end up going underground to the diatreme pipe, below the already worked area.\nHave drilled 3500’ down - not much gold, but did find carbonized wood!  The carbonized log is though to have been originally a tree caught up in an eruption by the Cripple Creek Volcano, and got incorporated in the diatreme breccia.\n300,000 ounces of gold per year is produced here.  They’ve just passed the 3 millionth ounce of gold for the district.\nPorphyritic phonolite bodies here have narrow rooted zones and they spread out above the root zones.\nThe mining area mostly has near-vertical features.  There are some flat-lying sills.\nThere are syenite bodies in the diatreme - they are not exposed at the surface - they are pretty broken up.\nAn aphanitic phonolite dike, the Bluebird Dike, is in the main Cresson Pit.\nThere are 3 to 4 old, very long drain tunnels that kept the original subsurface mines free of water.  Those mines tracked productive veins.  The tunnels come out in the Squaw Gulch area.  So, no water problems in the present mines.\nPresident Franklin Delano Roosevelt shut down the Cripple Creek District at one time - all nonessential mining was stopped during World War II.\nThe lamprophyre breccia body bifurcates at depth - it has a pair of pant legs.\nDrill holes through the pant legs didn’t have much gold, but they are only small pinprick drill holes.  Would like to redrill them.\nCurrent pit operations - expect to bottom out at 1000’-1200’ depth.  The expected life of the current mine is to 2012.\nOld underground workings consistently go through the gradient between low & high resistivity areas.\nAu:Ag ratios in the area range from 1:1 to 10:1.\nThe average grade of gold ore here is 2\u002F3 of a ppm.\nThe modern land surface is ~100 to 1000-2000 meters below the level of the original active volcanic surface.\n\u003C\u002Fp>\n\u003Chr>\n\u003Cp>Geologic unit: Cripple Creek Diatreme, Early Oligocene, 32 Ma\n\u003C\u002Fp>\nLocality: Cresson Pit, north of the town of Victor, Cripple Creek Mining District, southern Teller County, central Colorado, USA","James St. John",1829,{"id":951,"source_url":952,"license_code":944,"credit_html":953,"title":954,"description":955,"author":948,"original_width":956,"original_height":957},79638,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=97611324","James St. John, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=97611324\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Fluorite veins in pyritic phonolite (Cripple Creek Diatreme, Early Oligocene, 32 Ma; Rosetta Mine, Cripple Creek Mining District, Colorado, USA) 2.jpg","Fluorite veins in pyritic phonolite from the Oligocene of Colorado, USA.\n\u003Cp>The Cripple Creek Gold District of central Colorado is famous for its unusual gold and silver mineralization.

The dominant lithology at Cripple Creek is phonolite, a scarce, alkaline, intermediate, extrusive igneous rock.  Cripple Creek gold can be found in its native state (Au), but it typically occurs in the form of gold telluride minerals: for example, sylvanite - (Au,Ag)2Te4, calaverite - AuTe2, petzite - Ag3AuTe2, krennerite - (Au,Ag)Te2, and nagyagite - Pb5Au(Sb,Bi)Te2S6).  Silver also occurs in some Cripple Creek minerals, including sylvanite, petzite, krennerite, hessite - Ag2Te, tennantite - (Cu,Ag,Fe,Zn)12As4S13, acanthite - Ag2S, and argentian tetrahedrite - (Cu,Fe,Ag,Zn)12Sb4S13.\n\u003C\u002Fp>\u003Cp>Geologic unit: Cripple Creek Diatreme, Early Oligocene, 32 Ma\n\u003C\u002Fp>\nLocality: Portland Mine, Cripple Creek Mining District, town of Victor, central Colorado, USA",2625,1928,{"id":1178,"source_url":1179,"license_code":944,"credit_html":1180,"title":1181,"description":1174,"author":948,"original_width":1182,"original_height":1183},13655,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=85924661","James St. John, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=85924661\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Calaverite-krennerite-fluorite vein (Cripple Creek Diatreme, Early Oligocene, 32 Ma; Portland Mine, Victor, Colorado, USA) 3.jpg",2959,2091,{"id":1185,"source_url":1186,"license_code":728,"credit_html":1187,"title":1188,"description":1189,"author":775,"original_width":1190,"original_height":1012},15346,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=10177496","Robert M.

The tetrahedrite occurs as sharp , metallic crystals and may actually be overtopping large bornite crystals, it seems. The piece is very nearly pristine with but a few faint marks of wear seen by the educated eye only, and NO restoration or repairs whatsoever. The large central crystal is 5 cm across, and it is draped with fluorite and smaller rhodo crystals. The color I would rate as an 8.5 on a scale of 10 - and I can say honestly that it is what we called good color back when they were being mined - as opposed to what often passes for \"acceptable color\" on specimens I see at market today. The lustre is high, and the color saturation is uniform. This is an EXCELLENT piece overall, and has a huge amount of color for the price (again, considering what else I have seen on the market these days). The fluorites are sparkling and a nice lavender hue, in person. I purchased this piece for my private collection, of fine large Sweet Home rhodochrosite specimens, in 2006 at the Munich show. I have held it since, and am selling a few of my private collection rhodochrosites now only to finance acquiring a yet larger specimen.

A piece from this pocket, from the Kosnar collection, was on a recent Min Record cover, and this piece comes from the same lot, having identical color in person. The color is an intense red-maroon hue, with a touch of purple at the barest edges of the crystals as you can see in the photo...really deeper than red or pink fluorite from other locales.

Telluride species from this area are highly sought after by collectors, and it is well justified as some superb examples are known from the various mines in the area. This specimen hosts a few small, excellent quality sharp, lustrous, tabular, striated, monoclinic crystals of the rare Gold Telluride, Calaverite which have a bronzy hue. The crystals have a classic association (for this mine) of purple Fluorite and are sitting against grey Quartz matrix on matrix. The largest Calaverite crystal measures a few mm in length which is typical for the species and the locality, but an association with purple Fluorite is not typical. These specimens are very difficult to obtain, and considering that the majority of them were mined over 100 years ago, the only source for specimens is old collections. Ex.

The fluorite is complete all around and nearly pristine (just one very slightly dinged tip, hard to see). These pieces have been priced at, and sold, for big money - the reason being obvious in person when you compare the color saturation and gemminess\u002Ftransparency on one from this pocket, to previous finds or the general \"Chamonix pink\" style. This pocket will stand on its own merits, as one of the great Alpine finds, I believe. Pink or red fluorite is always pricey, but in context, for the quality compared to the norm, these are worth it in my opinion.

Cripple Creek gold can be found in its native state (Au), but it typically occurs in the form of gold telluride minerals: for example, sylvanite - (Au,Ag)2Te4, calaverite - AuTe2, petzite - Ag3AuTe2, krennerite - (Au,Ag)Te2, and nagyagite - Pb5Au(Sb,Bi)Te2S6).

word *fluorescence* exists because this mineral does. The naming came late — the mineral's story starts much earlier.\n\nPliny the Elder describes the stone in book 37 of his *Naturalis Historia*. He calls it a precious material with purple and white mottling, prized by the Romans for carved objects[1].\n\nIn 1529, the mining scholar Georgius Agricola gave fluorite its first written technical name: *Flussspat*[2]. The compound joined German *Fluss* (smelting flux) and *Spat* (a crystalline mineral). Latinised as *fluorspar*, the name reflected what miners did with the stone. Its low melting point turned it into a flux that helped harder ores give up their metals.\n\nThe Castleton mines in Derbyshire later produced a famously banded purple-blue variety known as *Blue John*, used for ornamental vases and other objects[3].\n\nIn 1797, the Italian mineralogist Carlo Antonio Galeani Napione coined the modern name *fluorite* from the Latin *fluere* — *to flow*[4]. The name kept the same flux-related sense.\n\nIn 1852, the physicist George Gabriel Stokes named the phenomenon of *fluorescence* after fluorite[5]. The element fluorine, too, takes its name from the mineral[6].","claude-opus-4-7","1.7.0","2026-06-01 14:30:52",{"markdown":2028,"model_version":2024,"prompt_version":2025,"reviewed_at":2029},"Fluorite gives the steel industry its flux and the chemical industry its fluorine source. Dissolved in sulfuric acid, the mineral releases hydrogen fluoride — a commodity chemical at the start of the fluorine supply chain[1]. Crushed into metallurgical grade — 60 to 85 percent CaF₂ — it goes into steel furnaces as a flux[2]. There it lowers the melting point of the raw materials.\n\nThe aluminium industry uses fluorite for the same flux purpose. The mineral also becomes aluminium fluoride and synthetic cryolite for aluminium smelting[3].\n\nFluorite feeds opalescent glass — the milky, decorative glassware — and the enamel coatings on iron and steel enamelware[4].\n\nOptical-quality fluorite has a small but specialised role. Its anomalous partial dispersion of light suits it to apochromatic lenses — high-grade camera and microscope optics designed to eliminate colour fringing[5].\n\nChina and Mexico are the world's leading producers; substantial deposits also lie in Russia, Brazil, and Spain[6].","2026-06-01 14:33:42"]
