TSV
Mineral Classification (Nickel-Strunz) - TSV
The Nickel-Strunz classification is a mineral classification system based on chemical composition, introduced by German mineralogist Karl Hugo Strunz in 1941. Based on the anion composition of minerals, it categorizes them into 10 classes: native elements, sulfides, halides, oxides, carbonates, borates, sulfates, phosphates, silicates, and organic compounds. This classification is officially supported by the IMA Commission on New Minerals and Mineral Names (CNMNC) and is widely used in mineralogical databases worldwide.

01 native-elements Native Elements Minerals composed of single elements or their alloys. ["Native Gold","Diamond","Native Copper","Sulfur"]
02 sulfides-sulfosalts Sulfides and Sulfosalts Minerals formed by the combination of sulfur with metallic elements. ["Sphalerite","Galena","Pyrite","Enargite"]
03 halides Halides Minerals formed by the combination of halogen elements (fluorine, chlorine, etc.) with metals. ["Fluorite","Halite","Chlorargyrite","Cryolite"]
04 oxides Oxides Minerals formed by the combination of oxygen with metallic elements, including hydroxides. ["Spinel","Magnetite","Hematite","Corundum"]
05 carbonates-nitrates Carbonates and Nitrates Minerals containing carbonate or nitrate ions. ["Calcite","Malachite","Dolomite","Siderite"]
06 borates Borates Minerals primarily composed of boron and oxygen. ["Borax","Ulexite","Colemanite","Howlite"]
07 sulfates Sulfates, Chromates, Molybdates and Tungstates Minerals containing sulfate, chromate, molybdate, or tungstate ions. ["Gypsum","Barite","Crocoite","Scheelite"]
08 phosphates-arsenates-vanadates Phosphates, Arsenates and Vanadates Minerals containing phosphate, arsenate, or vanadate ions. ["Apatite","Turquoise","Vanadinite","Mimetite"]
09 silicates Silicates The most diverse and abundant mineral group, primarily composed of silicon and oxygen. ["Quartz","Feldspar","Mica","Tourmaline","Kaolinite"]
10 organic-compounds Organic Compounds Minerals primarily composed of organic compounds. ["Mellite","Carpathite","Whewellite","Formicaite"]
