Hemimorphite is a silicate mineral with zinc as the main component. 含まれています 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, だからそれはまた呼ばれます […]
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, マグネシウム, クロム, 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 […]

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. The […]

Actinolite is a chain-like silicate mineral of magnesium, 鉄, カルシウム, sodium and aluminum containing hydrogen and oxygen. It is a kind of minerals in the hornblende group and has a similar relationship with Tremolite. . It has two variants. One is that actinolite and tremolite form a cryptocrystalline, tough and dense mass called nephrite; the […]
Jadeite is a commercial name. 実際には, it is a kind of rock composed mainly of jadeite.
