| 摘 要： | 贵州修文县干坝铝土矿区位于黔中铝土矿带,其矿体形态呈似层状,赋存于下石炭统九架炉组(C1j j)中,铝土矿体的规模与铝土矿岩系的厚度成正比,含矿岩系厚度大,则矿体规模大。而含矿岩系的厚度则受古喀斯特侵蚀面起伏状态控制,低洼处厚度大,凸起处厚度薄。该矿床类型属沉积型铝土矿矿床。

| Abstract: | Ganba bauxite orefield in Xiuwen,Guizhou is in Central Guizhou bauxite zone.The orebody is stratoid in Lower Carboniferous JiujialuFormation(C1jj).The scale of bauxite deposit is in direct propotion to the thickness of bauxite rock series,which is controlled by the erosion state of karst,ie thick in the concave;thin on the convex.It is a sedimentary bauxite deposit. |
