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.

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.

How to Tell If Gold is Real with Vinegar Treasure Pursuits

Gold is unaffected by vinegar because it is a stable metal and will not react with oxygen. That means it will not change color, develop crystals, or disintegrate. If the sample is iron pyrite (Fool''s Gold) or chalcopyrite, it may remain the color of gold, but will begin to form crystals while it is submerged.
