The thickness of ore-bearing stratum of Huangping changed a lot,it perhaps mean there are many unusual sedimentary controlling factors.In this paper,the metallogenic relation between ancient karst and bauxite in Huangping area,no obvious control is found to the ore-bearing stratum thickness for ancient karst.Meanwhile,the bauxite deposit with ore-bearing stratum and thickness of aluminium-bearing stratum,especially the thickness of ore-bearing stratum in ancient karst depression is bigger,the orebody is thick and the A/S is higher.The conclusion shows that the ancient karst is one important factor for controlling bauxite deposit.
