Abstract: The Wachapo bauxite deposit exists in time of Paleozoic erathem carbonas rock unconformity surface,accepts deposition disconnection controlling soft and floury strictly.The large-scale bauxite deposit is composed of 3 ore belts,more than 30 ore bodies,and is one of the main rich aluminium(sticky) ore belts in Henan province.The laterate-rization and mineral deposit forms are relative closely to the damp tropical climate;the depression unequal in size on the surface and dissolving fighting against the allocation are the locating space of the bauxite deposits.That the bay lago on depo sits each other is the advant age of the bauxite deposit formation.The research shows that the mineral deposit belongs to marine facies cause of formation short distance carry-machinery deposition give first place to bauxite type.
