iron pyrite sulfur

Pyrite

Pyrite (iron disulfide, FeS2) is typically a secondary mineral in small quantities of other rocks and ore deposits. The diagnostic physical properties of pyrite are brassy metallic luster, black streak, brittle fracture, hardness greater than that of glass, absence of cleavage and it is nonmagnetic. The crystalline structure of pyrite can …

What's the Difference Between Pyrite and Gold? | HowStuffWorks

Pyrite is different. Unlike gold, it's a compound made up of two different elements: iron and sulfur. That's why it's often referred to by the name "iron sulfide." Scientists write out pyrite's chemical formula as "FeS 2." You see, iron and sulfur's chemical symbols are, "Fe" and "S," respectively.

Pyrite

Pyrite. Commonly called fool's gold, pyrite is the Earth's most abundant sulfide mineral. Recognized for its brass-yellow color which resembles that of gold, pyrite is a source of iron and sulfur and is used for the production of sulfuric acid. Some types of pyrite contain enough microscopic gold to warrant mining them as a gold ore.

Storm-driven variations in depositional environments modify pyrite

The sulfur isotopic composition of marine pyrite (δ 34 S pyr) is one of the major geochemical tools to reconstruct global changes in Earth's surface environment.Storm-driven variations in depositional environments, however, can play key roles in modifying the δ 34 S pyr signal. Here we present δ 34 S pyr values in a complete …
