摘要
李家田铝土矿床赋存于下二叠统梁山组,与下伏地层寒武系呈平行不整合接触,其直接底板为铁质粘土岩,顶板为铝土岩或栖霞灰岩。矿体呈层状,矿石质量较好,铝硅比5.6,含铝矿物以—水硬铝石为主。矿床属红土—沉积型。
The Lijiatian bauxite deposit is hosted in Liangshan Fm. of Lower Permian Series which contacts the underlying Cambrian strata psuedocomformably. Its direct bottom wall is ferro-alumineous shale and the hanging wall is bauxitic rock or Qixia Fm.1 imestone. Its orebodies take the shape of stratiform with good quality of ore and the Al/Si ratio is 5.6. The aluminum-bearing minerals are mainly diaspore.The deposit should belong to laterite-sedimentary type.
