Apatite is a calcium phosphate mineral with complex chemical composition, often containing cerium, uranium, thorium and rare earth elements. According to the different additional anions, it is divided into fluorapatite, chloroapatite, hydroxyapatite and There are many varieties of strontium apatite and so on. They have a similar relationship with each other, and fluorapatite is usually […]
Kyanit, whose English name is Kyanite, is derived from the Greek Kyanos, which means “Blau”. It also has another English name, Kisthene, which also comes from Greek, which means “double” Und “Stärke”. It refers to different hardness. It shows one of the biggest characteristics of kyanite, das heißt, the product is in different directions on […]
Iolite, whose English name is Iolite, comes from the Greek word, meaning “violet”, indicating the gem-level color characteristics. It also has several English names, one of which is Cordierite, named after the French geologist who first described the mineral in the 19th century, Pierre Louis Dental Die (PLCordier); the second, Dichroite, also from In Greek, […]
Hemimorphite is a silicate mineral with zinc as the main component. It contains 53.7% zinc and sometimes contains a small amount of aluminum and iron. It is an important mineral of metallic zinc, and only a few colorless and transparent crystals are used as gems. Hemimorphite belongs to the orthorhombic crystal system, and the crystals […]
Pyrite, the English name Pyrite, comes from Greek and means “spark”, because this mineral emits sparks when hit by hard objects such as steel. Because the surface of pyrite is yellow-brown, it has a strong metallic luster on the crystal surface or polished surface, and is often mistaken for gold, so it is also called […]
The staurolite is a hydrous silicate mineral of aluminum and iron. It belongs to the monoclinic or pseudorhombic crystal system. The crystals are well developed and are short columnar. They usually have a cross with an angle of 90° or an X with an angle of 60°. Shape through the double crystal. The staurolite has […]
Epidote is a kind of hydrous calcium aluminosilicate mineral with island structure. Because its composition often contains various trace elements such as manganese, magnesium, Chrom, sodium and potassium, there are many kinds of similar substitutes, such as It is rich in manganese as monedrite, chromium is contained in chromium epidote, and calcium is replaced by […]
The molybdenum lead mine, the English name Wulfenite, is named after the Austrian mineralogist Franz Wulfen (F.X.Wulfen, 1728-1805). Molybdenite, also called color molybdenum, is a lead molybdate mineral, belonging to the tetragonal crystal system, and the crystals are in the shape of tetragonal plates. It has grease luster to diamond luster, transparent bis durchscheinend, Und […]
Sodalite is a chlorine-containing sodium aluminosilicate mineral, sometimes containing potassium in its composition. It belongs to the sodalite group in mineralogy. In addition to sodalite, there are zoisite, both crystals. The structure is the same, but the additional anions are different, but the properties are very similar. Sodalite belongs to the equiaxed crystal system. Der […]
