Wisconsin Geological & Natural History Survey » Pyrite

— Pyrite occurs in limestone as tiny, sometime iridescent, crystals in vugs and on joint surfaces at the Ripon Lime and Materials Company Quarry, NW sec. 20 T.16N R.14E., just west of Ripon. FOREST COUNTY: Pyrite is a major component of the massive sulfide ore and underlying stringer ore at the Crandon massive sulfide deposit near Little Sand Lake.

pyrite | Properties & Facts | Britannica

Pyrite, a naturally occurring iron disulfide mineral. The name comes from the Greek word pyr, ''fire,'' because pyrite emits sparks when struck by metal. Pyrite is called fool''s gold; to the novice its color is deceptively similar to that of a gold nugget.

How do pyrite and pyrrhotite damage building …

Pyrite and pyrrhotite are minerals known as iron sulfides. When iron sulfides are exposed to water and oxygen, a series of chemical reactions breaks down the iron sulfides and forms new minerals called sulfates. These sulfates take up more space than the original iron sulfides. As they grow, the new sulfate minerals push against the surrounding rock, causing it to swell and crack.

Pyrite: Mineral information, data and localities.

Pyrite Group. The isometric (cubic) polymorph of orthorhombic marcasite pare UM1997-43-S:Fe. Pyrite is a very common mineral (also one of the most common natural sulfides, and the most common disulfide), found in a wide variety of geological formations from sedimentary deposits to hydrothermal veins and as a constituent of metamorphic rocks.

What Is the Chemical Formula for Limestone?

 · Pure limestone is made up of two component minerals: calcium carbonate and calcium-magnesium carbonate. The chemical formula for calcium carbonate is CaCO3. The chemical formula for calcium-magnesium carbonate is CaMg (CO3)2. Calcium carbonate is commonly known as calcite,and calcium-magnesium carbonate is commonly known as dolomite.

Deep abiotic weathering of pyrite | Science

 · Pyrite, also called fool''s gold, is an iron sulfide mineral that is very commonly found in rock but is almost nonexistent in sediments today. Pyrite oxidizes quickly and is a major source of sulfur to the ocean, but it is also a proxy for the oxygen content historically in Earth''s atmosphere. Gu et al. conducted a set of detailed observations of the pyrite oxidation process in a shale unit ...
