Oct 01, 2016 1. Introduction. Apatite is a ubiquitous accessory component in igneous rocks, as well as a common hydrothermal mineral. It generally hosts the majority of the whole rock P and a significant portion of the total budget of rare earth elements (REE) and Y (Piccoli and Candela, 2002). Apatite chemistry is complex and can be defined by the formula A 5 (XO 4) 3 Z (Pasero et al. , 2010), where A isRequest PDF on ResearchGate Apatite in Igneous Systems Apatite is a minor but ubiquitous mineral in most igneous rocks.

Apatite crystals coexisting with liquid or with vapour in the system CaOCaF2P2O6H2OCO2 are equant whereas those precipitated from a liquid during a quench are greatly elongated parallel to the caxis and they exhibit skeletal forms. Basic rocks in the Karroo volcanic succession of Southern Rhodesia contain apatite crystals with forms very similar to the synthetic quench apatites.

Abstract. Apatite crystals coexisting with liquid or with vapour in the system CaOCaF 2P 2 O 6H 2 OCO 2 are equant whereas those precipitated from a liquid during a quench are greatly elongated parallel to the caxis and they exhibit skeletal forms. Basic rocks in the Karroo volcanic succession of Southern Rhodesia contain apatite crystals with forms very similar to the synthetic quench Apatite is a minor but ubiquitous mineral in most igneous rocks. Although the modal proportion of apatite in common rocks is generally low, it can reach high concentrations in enclaves, cumulates, and other rocks of low abundance (i. e. , rocks that constitute a small volume of apatite in igneous systems Apatite is one of a few minerals produced and used by biological microenvironmental systems. Apatite is the defining mineral for 5 on the Mohs scale. Hydroxyapatite, also known as hydroxylapatite, is the major component of tooth enamel and bone mineral.
