The mineral pyrite (/ ˈ p aɪ r aɪ t / PY-ryte), [6] or iron pyrite, also known as fool's gold, is an iron sulfide with the chemical formula Fe S 2 (iron (II) disulfide). Pyrite is the most abundant sulfide mineral .
The density of pyrite also means the fool's gold material thoroughly filled in tiny areas where the arthropod's body once lay in sediment − including internal body parts, scientists said.
Fool's gold – a mineral, iron disulfide or pyrite; can form oil of vitriol on contact with water and air. Fulminating silver – principally, silver nitride, formed by dissolving silver(I) oxide in ammonia. Very explosive when dry. Fulminating gold – a number of gold based explosives which "fulminate", or detonate easily.

People living in the Pacific nation are divided on whether to push ahead with deep-sea mining for polymetallic nodules.
The specimen was preserved in pyrite, or fool's gold, making it easy to produce 3D models of the fossil using CT scans. Credits: Luke Parry/Yu Liu/Ruixin Ran (3D models). - courtesy Luke Parry/Yu ...
Despite being nicknamed fool's gold, pyrite is sometimes found in association with small quantities of gold. Gold and arsenic occur as a coupled substitution in the pyrite structure. In the Carlin–type gold deposits, arsenian pyrite contains up to 0.37% gold by weight. [5] The possible replacement of (Al 3+) 2 by Fe 2+ Ti 4+ in Corundum. [1 ...
Chalcopyrite (/ ˌ k æ l k ə ˈ p aɪ ˌ r aɪ t,-k oʊ-/ [7] [8] KAL-kə-PY-ryte, -koh-) is a copper iron sulfide mineral and the most abundant copper ore mineral. It has the chemical formula CuFeS 2 and crystallizes in the tetragonal system.
