Pyrite | Common Minerals

Pyrite''s sulfur content is one of its potential gifts, but it also raises some environmental concerns. As water moves through a pyrite-bearing rock, the pyrite''s iron component may be oxidized, releasing its sulfur to form sulfuric acid. In natural settings this is seldom a concern, but pyrite-rich waste from mining operations can ...

Pyrite: The mineral pyrite information and pictures

Pyrite was once used as a source of sulfur, but is now only a minor ore for both sulfur and iron. Pyrite from some localities is auriferous, and therefore is used as an ore of gold in gold-bearing localities.Pyrite was polished by the Native Americans in the early times and used as mirrors. Today, it is used as an ornamental stone, as well as a very popular stone for amateur collectors.

Sedimentary pyrite sulfur isotopes track the local dynamics of the ...

Sulfur cycling is ubiquitous in sedimentary environments, where it mediates organic carbon remineralization, impacting both local and global redox budgets, and leaving an imprint in pyrite sulfur isotope ratios (δ 34 S pyr) is unclear to what extent stratigraphic δ 34 S pyr variations reflect local aspects of the depositional environment or microbial activity versus global sulfur …
