phosphate in igneous rocks

Phosphate Minerals in Terrestrial Igneous and

Phosphorus is a ubiquitous although minor component of most igneous and metamorphic rocks. Under the normal oxidative conditions of the Earth’s crust and upper mantle, phosphorus is present as phosphates, and Koritnig (1978) lists over 200 phosphate minerals. Nonetheless, in common igneous and metamorphic rocks phosphate mineral diversity is ...

Phosphate Rocks: A Review of Sedimentary and Igneous ...

Phosphate rocks are a vital resource for world food supply and security. They are the primary raw material for phosphoric acid and fertilizers used in agriculture, and are increasingly considered to be a potential source of rare earth elements. Phosphate rocks occur either as sedimentary deposits or igneous ores associated with alkaline rocks.
