簡介:"主要由鐵和硫所構成,偶爾也含有少量的銅和砷。屬於斜方晶系,與等軸晶系的黃鐵礦係屬同質異形體。 新鮮面呈淺銅黃色,經風化後,可轉變為淺青銅黃色。因白鐵礦較黃鐵礦更易風化崩解,因此,在自然界白鐵礦的數量遠較黃鐵礦為少。 與黃鐵礦相似,其主要是用來提煉硫。礦物硫化物及硫鹽白鐵礦Marcasite Sulfides and SulfosaltsMarcasite consists primarily of iron and sulfur and occasionally little copper and arsenic. Of orthorhombic crystal system, it is polymorphic with pyrite of isometric crystal system.Fresh marcasite is light brass-yellow or light bronze-yellow after weathering, whose strength is greater to marcasite than to pyrite. Hence, there is by far less marcasite than pyrite in Nature.Similar to pyrite, the major use of marcasite is to extract sulfur."
