The main component of cassiterite is tin oxide, which is an oxide mineral, often containing trace elements such as iron, niobium, tantal, titanium and manganese. Cassiterite is a tetragonal crystal system. The crystals are often short columnar, slender columnar or double cone-shaped, and the conical aggregates are block, granular or kidney-shaped; with diamond luster to […]

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 […]
Kyanite, whose English name is Kyanite, is derived from the Greek Kyanos, hvilket betyder “blå”. It also has another English name, Kisthene, which also comes from Greek, hvilket betyder “double” og “styrke”. It refers to different hardness. It shows one of the biggest characteristics of kyanite, det er, the product is in different directions on […]
Iolit, hvis engelske navn er Iolite, kommer fra det græske ord, mening “violet”, angiver farveegenskaberne på ædelstensniveau. Den har også flere engelske navne, en af dem er Cordierite, opkaldt efter den franske geolog, der første gang beskrev mineralet i det 19. århundrede, Pierre Louis Dental Die (PLcordier); den anden, Dichroite, også fra På græsk, […]
Hemimorphite is a silicate mineral with zinc as the main component. Den indeholder 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, så hedder det også […]
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 er en slags vandholdigt calciumaluminosilikatmineral med østruktur. Fordi dens sammensætning ofte indeholder forskellige sporstoffer såsom mangan, magnesium, Krom, natrium og kalium, der er mange slags lignende erstatninger, såsom Den er rig på mangan som monedrit, krom er indeholdt i kromepidot, 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, gennemsigtig til gennemsigtig, og […]
