Sphalerite rock
Sphalerite (sometimes spelled sphaelerite) is a sulfide mineral with the chemical formula (Zn,Fe)S. It is the most important ore of zinc . Sphalerite is found in a variety of deposit types, but it is primarily in sedimentary exhalative , Mississippi-Valley type , and volcanogenic massive sulfide deposits. ⬇ Baixe fotos de Hematita no enorme banco de imagens Milhões de fotos Imagens, ilustrações livres de royalties de alta qualidade a preços acessíveisSphalerite mineral is in group of Sulfide mineral that is formula ( (Zn, Fe)S).It is the principal ore of zinc. Pure sphalerite is colorless and rare. Normally, iron is present, causing the color to vary from pale greenish yellow to brown and black with increasing iron content. When iron content is high it is an opaque black variety, marmatite.
