4.1" Marcasite Crystal Cluster - Morocco

This is an aggregation of marcasite crystals that formed from what appears to be a calcite matrix, collected from the Oumjrane area of Morocco.

Marcasite is an iron sulfide mineral with the chemical formula FeS2. It is similar to pyrite in both its chemical composition and appearance, but it forms an entirely different crystal structure and is much more reactive to humidity. It is often found within sedimentary rock and hydrothermal deposits, and at one point was used for its sulfur content.
