Pyrite has the same chemical formula as the rarer mineral Marcasite, but it crystallizes in a different crystal system, thereby classifying it as a separate mineral species. Aggregates of iron sulfide (FeS 2 ) where the crystal structure cannot be determined without complex analyzing material may be wrongly labeled by dealers.

Pyrite is usually found associated with other sulfides or oxides in quartz , sedimentary rock, as well as in coal beds and as a replacement mineral in fossils , but has also been identified in the sclerites of scaly-foot gastropods Despite being nicknamed fool's gold, pyrite is sometimes found in association with small quantities of gold.

2021-10-18 Pyrite (FeS 2) is the most abundant sulfide mineral and usually occurs both as a primary and secondary mineral according to its genesis.Lattice substitution of some minor and trace elements such as nickel, cobalt, arsenic, lead, and gold are also the results of this ore genesis and geographical location [] and may have an impact on pyrite floatability [].

Occurrence of Pyrite . Formed under a wide variety of conditions. In hydrothermal veins as very large bodies, as magmatic segregations, as an accessory mineral in igneous rocks, in pegmatites; in contact metamorphic deposits, also in metamorphic rocks; as diagenetic replacements in sedimentary rocks.

Pyrite. Pyrite (iron sulfide), with its brassy-yellow color and bright metallic luster, is the one-and-only Fools Gold! Add to its color and luster an amazing variety of striking crystal forms, and it’s understandable why it’s one of the most collectable minerals. The famous perfect cubes from Spain are especially treasured among collectors.
