The geochemistry of the major ingredients is a precise translation of the mineral composition. The constituents that exist only in the francolite structure are P 2 O 5 and F. In average, the F/P 2 O 5 ratio in the Egyptian phosphorites is about 1.12. According to McConnell (), the introduction of F into the apatite structure has several important Egyptian limestone, shaped by eons of geological processes, is a sedimentary rock composed primarily of calcite.
