摘要
凯里黄平地区含矿岩系地层厚度变化大,说明可能存在着许多非正常沉积的控制作用因素。本文对凯里黄平地区古岩溶与铝土矿的成矿关系进行研究,发现岩溶古地貌对铝土矿含矿岩系的厚度有明显控制作用,同时研究表明,铝土矿与含矿岩系呈正相关关系(r=0.88),亦与含铝岩组的厚度呈正相关关系(r=0.91),尤其是在古岩溶凹地中含矿岩系厚度较大,矿体亦较厚,且铝硅比(A/S)相对较高。结论表明古岩溶是铝土矿的重要控制因素之一。
The thickness of ore - beating stratum of Huangping changed many unusual sedimentary controlling factors. In this paper, the a lot, it perhaps mean there are metallogenic relation between ancient karst and bauxite in Huangping area, no obvious control is found to the ore - beating stratum thickness for ancient karst. Meanwhile, the bauxite deposit with ore - bearing stratum and thickness of aluminium - beating 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.
