摘　　要：本文通过对川主庙铝土矿矿区含矿岩系岩性组合特征及其与顶底板之间的关系进行分析,结合古地理等情况,进一步证明了黔中川主庙铝土矿成矿物质来源主要来源于基底湄潭组、桐梓组泥页岩(少量来源于白云岩、灰岩)、及黔中铝土矿矿床成因为:"母岩风化剥蚀-原地堆积(部分搬运沉积)-进一步风化淋滤-成矿"的观点。Through the analysis on the relationship between the lithologic association features of the ore-bearing rock series of Chuanzhumiao bauxite deposit and its roof and floor, along with paleogeographic information, this paper further demonstrates that the sources of the ore-forming material of Chuanzhumiao bauxite deposit mainly come from shale （a minority come from dolomite and limestone） of Meitan Formation and Tongzi Formation. And it also illustrates the idea that the ore genesis of Chuaazhumiao bauxite deposit is like this： weather-worn of the parent rock--autochthonous deposit accumulation （some are transported deposit accumulation）--weathering leaching--mineralization.
