矿床地质简况本区铝土矿分原生矿和堆积矿两大类.后者是前者经过风化剥蚀改造在原生矿附近低凹处堆积而成.原生矿位于上二迭统合山组灰岩底部,下伏二迭系茅口灰岩的侵蚀面上,上覆顶板为炭质页岩和煤层;储量大,但含硫高,现尚未开采.具有工业意义的堆积铝土矿,赋存于第四系下更新统粘土层中.其规模和形态多受地形控制.只有在凹地及缓坡矿石才有利保存.平面上,矿体展布宽大但不规则.剖面
Geological profile of the deposit The bauxite in this area is divided into two major categories of primary and secondary deposits, the latter is the former through weathering and denudation alteration in the low-lying deposits near the primary deposits from the primary ore located in the Upper Permian Lushan limestone bottom, The next two Diego Maokou limestone erosion surface, the overlying roof for the carbonaceous shale and coal seam; reserves of large, but high sulfur, is not yet mining.Industrial significance of the accumulation of bauxite, hosted in the In the fourth line of Lower Pleistocene clay, the scale and morphology are mostly controlled by the terrain, which is only conserved in the depression and gentle slope ore.On the plane, the orebody is distributed widely but irregularly.
