摘　　要：修文比例坝铝土矿床属古风化壳壳沉积型铝土矿床,地处黔中—川南铝土矿成矿带之修文铝土矿矿带,东与小山坝铝土矿相接壤,是近年黔中地区发现的又一中型铝土矿床。铝土矿含矿岩系为下石炭统九架炉组,与下伏寒武系中上统娄山关群地层呈平行不整合接触,铝土矿矿层位于寒武系中上统娄山关群白云岩侵蚀面上。通过与小山坝铝土矿的稀土元素特征作对比,探讨其在沉积环境及成矿物源方面的相似性。By the proportion of dam sedimentarey bauxite deposit, it belongs to the ancient weathering crust shell type bauxite deposits, which is located in Guizhou-Sichuan bauxite metallogenic belt in bauxite ore belt in bordering east and hill dam bauxite. It is found in alias of Guizhou in recent years there is a medium-sized bauxite deposit. We know of bauxite ore-bearing rock series in the carboniferous nine furnace group. The LouShanguan group of lower FuHanWu is in upper strata to show parallel unconfomreity. It contacts bauxite deposits in the Cambrian system in upper middle Tianshan group of dolomite erosion surface. In this paper, the similarity between the sedimentarey environment and the mineralization source is discussed by comparing the rare earth elements in the bauxite mine.
