Apatite [Ca 5 (PO 4,CO 3) 3 (OH,F,Cl)] is the most abundant phosphate mineral, which accounts for more than 95% of all phosphorus in the Earth's crust and is found as an accessory mineral in most rock types 1. A rock may be best defined as any mineral or aggregate of minerals that forms an essential part of the Earth [].Apatite is …

rich sediment, phosphorite, chert and carbonate has been constant over time, but that the type of carbonate rock has shown a temporal variation. Dolomite is the only significant carbonate in Proterozoic and Cambrian sequences, whereas both limestone and dolomite occur in younger sequences. Some of the organic-rich phosphatic sediments are oil ...

The global production capacity of phosphate rock (also known as phosphorite) amounted to some 243 million metric tons in 2020, up from 226 million metric tons in 2016.

To use soft rock phosphate properly, always incorporate it into the soil before planting. You can also add it to a planting hole when repotting or planting trees. Adding it to the soil surface may not be as effective. If you have a well-established lawn and trees, scatter the rock phosphate over the landscape.

Radiolarian oozes tend to occur in the deep sea, under divergence zones in the open ocean. Despite the predominance in modern upwelling zones of diatoms, the association of chert, organic-rich rock, phosphorite, and glauconite is common in older rocks as well; the chert in these rocks is radiolarite or spiculite.
