Sulfide Mineral Pictures. Photo (c) Andrew Alden, licensed to About.com (fair use policy) Marcasite is iron sulfide or FeS 2, the same as pyrite, but with a different crystal structure.(more below) Marcasite forms at relatively low temperatures in chalk rocks as well as in hydrothermal veins that also host zinc and lead minerals.
Pyrite is a compound of iron and sulfur, iron sulfide. Depending upon the conditions under which it forms this mineral can form crystals of different shapes.

The understanding of iron sulfide formation under Earth surface conditions has largely been informed by extensive laboratory studies (see summary by Morse et al., 1987). Multiple potential pathways for sedimentary iron sulfide (pyrite) formation have been recognized. As summarized by Goldhaber (2003), these include (1) direct precipitation …
