This work consist to explore, locate and quantify variety of phosphorus mineral apatite Cl FCa3 (PO4)3, in nodules formed by sandstones are gray outdoor spread or scattered over the surfaces of terraces, plains and slopes located on the right bank of the river ICA, partially or totally covered by sand, silt, clay from wind, central shoal area that includes the hill Whale, an area west of the town of Ocucaje. The nodules described come from three sandy layers or horizons, different, consistent, failed and separated from each other 40m, outcrop in the cliffs of the escarpment or shoals; Whale, Central, white hills, Witch and Holy Well, located on the right bank of river ICA, section Ocucaje, located 35km. southwest of the city ICA. The calcium phosphate apatite is fluorine and chlorine in varying amounts, 7% of P2 O5 , in nodules are white sandstone gray or black, uneven tone, vitreous to greasy luster, Mohs hardness scale 5, conchoidal fracture, specific gravity 3.1 – 3.2, exceptional luminescence. This phosphate is mined in large quantities, in phosphate rocks (Rusia – EE.UU.) and phosphatic sands in Morocco is the world’s largest producer.Downloads
