At its simplest, a mineral is a naturally-occurring solid chemical.  Currently, there are over 6100 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 oxide minerals all contain one or more oxide anions (O-2).\n\u003C\u002Fp>\u003Cp>Hematite is a common iron oxide mineral (Fe2O3).  It varies in appearance, from nonmetallic-lustered and brick red-colored to metallic-lustered and silvery-gray colored to black-colored.  Brick red hematite is often powdery or finely granular or oolitic.  Silvery-gray hematite (micaceous hematite) is less common and results from mild to moderate levels of metamorphism.  Hematite ranges in hardness from soft to moderately hard (about 1 to 6 on the Mohs Hardness Scale).  Regardless of a specimen’s color or luster, hematite will always leave a brick red-colored streak, which is its most diagnostic physical property.\n\u003C\u002Fp>\n\u003Chr>\n\u003Cp>Exhibit info.:\n\u003C\u002Fp>\u003Cp>Cavradi Gorge is one of Switzerland's premier mineral localities.  \"Cavradi\", a well-illustrated book about the mineralogy of Cavradi written by local experts, was published in 2013.  For nearly 200 years, superb hematite and quartz crystals have been won from \"alpine clefts\" in the ravines on either side of Cavrado Gorge by local professional mineral collectors called \"Strahlers\".

The Coleraine formation is a Cretaceous period geological formation in Minnesota that contains sediments and fossils from the Western Interior Seaway approximately 90 million years ago. This layer was exposed by iron mining on the Mesabi Iron Range. This rock was found in Hill Annex Mine State Park in Calumet, MN. The image was taken with a ZEISS Smartzoom 5 microscope at 335X magnification using extended depth of field.","Rylan Bachman",1600,1300,{"id":711,"source_url":712,"license_code":492,"credit_html":713,"title":714,"description":715,"author":716,"original_width":717,"original_height":718},58600,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=146588327","Slashme, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=146588327\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Wollastonit Sphalerit Hämatit.jpg","Wollastonit Sphalerit und Hämatit (Wollastonit vielleicht unsicher), Fundort Grube St. Christoph, Breitenbrunn, Schwarzenberg, Sachsen","Slashme",4284,2886,{"id":720,"source_url":721,"license_code":529,"credit_html":722,"title":723,"description":724,"author":533,"original_width":725,"original_height":726},919,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=50402143","Robert M.

At its simplest, a mineral is a naturally-occurring solid chemical.  Currently, there are about 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 silicates are the most abundant and chemically complex group of minerals.  All silicates have silica as the basis for their chemistry.  \"Silica\" refers to SiO2 chemistry.  The fundamental molecular unit of silica is one small silicon atom surrounded by four large oxygen atoms in the shape of a triangular pyramid - this is the silica tetrahedron - SiO4.  Each oxygen atom is shared by two silicon atoms, so only half of the four oxygens \"belong\" to each silicon.  The resulting formula for silica is thus SiO2, not SiO4.\n\u003C\u002Fp>\u003Cp>The simplest & most abundant silicate mineral in the Earth's crust is quartz (SiO2).

before any written record, humans were grinding hematite to red powder. The earliest known human use comes from the Pinnacle Point caves in present-day South Africa, 164,000 years ago — possibly for social purposes[1]. Hematite residues turn up in graves 80,000 years old[2]. Near Rydno in Poland and Lovas in Hungary, red chalk mines worked by the Linear Pottery culture date to about 5000 BCE[3].\n\nThe mineral got its written name in classical Greece. Around 300–325 BCE, Theophrastus called it *aematitis lithos* — *blood stone* — for the colour of its ground powder[4]. The name may be the first ever applied to a mineral with the now-familiar **-ite** suffix[5]. In 79 CE, Pliny the Elder translated the Greek into Latin as *haematites*, meaning *bloodlike*, in allusion to that same red dust[6]. The pigment ground from the mineral was also known as *sil atticum*, another Latin name for the dark-red colour[7].\n\nThe Latin name carried into medieval Europe as *lapis haematites*. By the 15th century it had reached French as *hématite pierre*, the immediate ancestor of the modern English name[8]. Over the following centuries, writers simplified *haematite* by dropping the second *a* — a pattern that paralleled other words built on the same blood-root *haeme-*[9].","claude-opus-4-7","1.7.0","2026-06-01 16:19:00",{"markdown":1532,"model_version":1528,"prompt_version":1529,"reviewed_at":1533},"Hematite is, by an enormous margin, the world's primary iron ore. Its dominance comes from a high iron content of 70 percent and broad geological abundance[1]. Major sources include the Lake Superior basin in North America, Brazil's Minas Gerais district, Venezuela's Cerro Bolívar, and the Labrador–Quebec deposits of Canada[2]. From these deposits flows the iron that the modern steel industry consumes.\n\nGround to powder, the mineral remains in use as a pigment. *Red ochre*, the dark-red paint pigment, is still drawn from hematite for artist's colours and traditional finishes[3]. A purified form, *rouge*, is used to polish plate glass[4].\n\nThe mineral's density gives it a second industrial role. With its high density, hematite is an effective barrier against X-rays and is often incorporated into radiation shielding[5].\n\nPolished hematite is shaped into beads, tumbling stones, and other jewellery components[6].","2026-06-01 16:19:52"]
