To understand why sedimentary phosphate rocks (hereafter referred to as phosphorites) have elevated uranium contents we first need to understand what are they made of and why do they form in the first place Phosphorites are rocks that are made of apatite, a mineral with the formula $\ce{Ca5(PO4)3(F,Cl,OH)}$...

Hydroxyapatite Crystal

Does this patient have basic calcium phosphate crystal/hydroxyapatite deposition disease?
