pyrrhotite formed by in situ reduction of magnetite by pyrite and organic compounds; it could not have been formed by the large-scale introduction of reducing fluids, as isotopic evidence indicates that these metalimestones remained impermeable. At higher grades, some pyrrhotite probably also formed by the reaction of pyrite and Fe-bearing ...

Pyrrhotite - an overview | ScienceDirect Topics

Pyrrhotite is the stable iron sulfide for oxygen fugacities fO 2 < FMQ (fayalite (FeSiO 4) ↔ magnetite + quartz), whereas paramagnetic pyrite (FeS 2) is dominant under the more oxidizing conditions in the Earth's crust (Lorand et al., 2005). Martian meteorites contain about as much pyrrhotite as magnetite.

Savage River Iron Ore Deposits - Natural Phenomenon ...

Natural Phenomenon: Savage River Iron Ore Deposits Summary. The Savage River Iron Ore Deposits were discovered in 1877 but the area's isolation and apparently poor quality magnetite meant no mining resulted. In 1958 the Department of Mines drilled a few exploratory holes into the Precambrian aged mineralised strata sulphide.

What is the difference between Pyrrhotite and Magnetite ...

The difference between pyrrhotite and magnetite is that „pyrrhotite" is a weakly magnetic ferrous sulfide mineral, FeS and „magnetite" is a magnetic mineral, Fe3O4, one of the primary ores of iron. It has also been called lodestone. pyrrhotite magnetite Noun (mineralogy) A weakly magnetic ferrous sulfide mineral, FeS. Synonyms magnetic pyrites Hypernyms pyrite …

It is proposed that a substantial fraction of the magnetite, at least, resulted from the oxidation of troilite. Pyrrhotite is expected as a direct consequence of magnetite formation through this reaction. During thermomagnetic experiments on troilite, magnetite formation was observed at temperatures as low as 373 K, provided that the oxygen fugacity was held in the magnetite …

Pyrrhotite - Aegerine - Magnetite Archives - Heather Canyon

Pyrrhotite is a rare variety of iron sulfide that forms a brassy colored metallic mineral. In this rock from the Ukraine, pyrrhotite is associated with black magnetite and green-black aegerine in an igneous rock type – norite, a rock similar to "black granite", or gabbro. Pyrrhotite comes from the Greek work "pyrrhos", which means flame-colored. The norite rocks that contain ...
