Apatite, Phosphorite and Phosphate Rock Geology

Like limestone, phosphate rock is deposited in sedimentary basins where the influx of detrital material is relatively low. That allows the phosphate to accumulate with very little dilution from other materials. Where the dilution rate is high, phosphatic shales, mudstones, limestones, and sandstones will form instead of phosphate rock.

The maintenance of calcium and phosphate homeostasis involves intestinal, bone, and renal handling of these ions. Within the plasma, calcium circulates in different forms. Of the plasma calcium, approximately 40 percent is bound to albumin; 15 percent is complexed with citrate, sulfate, or phosphate; and 45 percent exists as the physiologically important ionized (or free) calcium.
