Apatite

Apatite is very common as an accessory mineral in igneous and metamorphic rocks, where it is the most common phosphate mineral However, occurrences are usually as small grains which are often visible only in thin section Coarsely crystalline apatite is usually restricted to pegmatites, gneiss derived from sediments rich in carbonate minerals, skarns, or marble Apatite is also found in clastic sedimentary rock as grains eroded out of the source rock Phosphorite is a phosphaterich sedimentary rockPhosphate Rock Rock phosphate or phosphorite is a nondetrital sedimentary rockthat contains high amounts ofphosphate minerals in the form of fluorapatite Ca5(PO4)3F and Phosphate Rock an overview ScienceDirect Topics
