Marcasite

FeS2
Element% marcasite
S 53.46 This is a reflected light micrograph of polished, carbon coated marcasite crystals. The identifying etched label, which is a feature of our standards, is invaluable for navigating in an electron beam instrument. Identical in composition to the more familiar mineral pyrite, marcasite is formed at low temperatures and is therefore more pure. Pyrite is to sulfides as quartz is to silicates - the most common - and therefore its composition is an essential part of any mineral standard set.
