Serpentinite - Wikipedia

Formation and petrology. Serpentinization is a geological low-temperature metamorphic process involving heat and water in which low-silica mafic and ultramafic rocks are oxidized (anaerobic oxidation of Fe 2+ by the protons of water leading to the formation of H 2) and hydrolyzed with water into serpentinite.

Magnetite - Wikipedia

Properties. In addition to igneous rocks, magnetite also occurs in sedimentary rocks, including banded iron formations and in lake and marine sediments as both detrital grains and as magnetofossils.

Redox and nonredox reactions of magnetite and hematite

1. Introduction. Stimulated by the recent paper of Ohmoto (2003) who discussed nonredox reactions for the conversion of iron oxides, a critical and brief review and comparison of nonredox and redox reactions in rocks will be undertaken.

Magnetite - New World Encyclopedia

Small grains of magnetite occur in almost all igneous rocks and metamorphic rocks. Magnetite also occurs in many sedimentary rocks, including banded iron formations. In many igneous rocks, magnetite-rich and ilmenite(a titanium iron oxide)-rich grains occur that precipitated together from magma.

Schist - Metamorphic rocks

Schist is a strongly foliated medium-grade metamorphic rock. It is characterized by an abundance of platy or elongated minerals (micas, chlorite, talc, graphite, amphiboles) in a preferred orientation.
