pyrite in mafic igneous rocks

pyrite | Properties & Facts | Britannica
Pyrite occurs in large deposits in contact metamorphic rocks. Deposits of copper-bearing pyrite are widely distributed and often of great size. They usually occur in or near the contact of eruptive rocks with schists or slates. Pyrite weathers rapidly to hydrated iron oxide, goethite, or limonite; pseudomorphs of goethite after pyrite are common. This weathering produces a characteristic yellow-brown stain or coating,Онлайн-запрос

While all intermediate and mafic igneous rocks may contain hornblende and clinopyroxene, hornblende is more common in diorite and andesite, and clinopyroxene is more common in gabbros and basalts. Gabbros and basalts may also contain olivine. Magnetite, ilmenite, and apatite are common as accessory minerals in mafic and intermediate rocks.

Iron is a common minor constituent of all continental igneous rocks; and occurs in minerals such as ilmenite, magnetite and pyrite, and ferro-magnesian silicates like olivine, pyroxene, amphibole, and biotite mica.

What are the minerals and Gems that found in the Igneous
Igneous rock, or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava.

Pyrrhotite is more reduced than pyrite and is the stable iron sulfide formed from magmas (Fig. 18.2B; Hall, 1986).

Mafic vs. Felsic
These are both made up words used to indicate the chemical composition of silicate minerals, magmas, and igneous rocks. Mafic is used for silicate minerals, magmas, and rocks which are relatively high in the heavier elements. The term is derived from using the MA from magnesium and the FIC from the Latin word for iron, but mafic magmas also are relatively enriched in calcium and sodium. Mafic
