ApatiteType Materials Apatite is generally a group of phosphate minerals consisting of high concentration of OH− F − and Cl − referred to as hydroxylapatite fluorapatite and chlorapatite respectively Actually it is a type of mineral named by German geologist in 1786
Apatite itself is a good source of phosphorus This becomes more aparent when examining its chemical formula Ca5 PO43 and either OH F or Cl Thus apatite’s role is a phisphorus source
mechanisms to increase phosphorus availability and facilitate uptake Raghothama 1999 Many soil fungi are able to solubilize phosphorus directly from minerals such as apatite Ca 10 PO 4 6 OHFCl 2 Both plantsymbiotic and freeliving soil fungi have been demonstrated to increase phosphorus uptake in plants through their biogeochemical activity
Apatite is the main source of phosphorus Phosphorus was previously extracted from crystalline Apatite but nowadays is extracted from enormous deposits of Apatiterich rock Apatite is essential in the manufacture of phosphate fertilizers and is very important in
Phosphate leached from guano phosphatizes the underlying rocks in some areas forming apatite where the host rock is limestone and forming aluminum or aluminumironphosphate minerals where the underlying rock is a silicate
High phosphorus contents are mostly a conse quence of the elevated apatite solubility in peralu minous granite melts The presence of inherited apatite crystals is of secondary importance Departures from Harrison and Watsons model can be corrected with the expression p fcorrected D fHW v ofactor 25 25 where P20w is the prediction of model and factorASI1 6429T

Because of the high solubility of apatite in basic magmas phosphorus can be confidently treated as an incompatible element in peridotite melting models Such models in combination with observed characteristics of basic lavas indicate that the upper mantle contains ∼200 ppm of phosphorus much less than the chondritic abundance of ∼900 ppm
What is Apatite Apatite is the name of a group of phosphate minerals with similar chemical compositions and physical properties They are an important constituent of phosphorite a rock mined for its phosphorus content and used to make fertilizers acids and chemicals Apatite has a relatively consistent hardness and serves as the index mineral for a hardness of five in the Mohs Hardness Scale
