| 摘 要： | 陕西已知铝土矿主要分布于陕西北部的府谷县、韩城市、铜川市、白水县一带,含矿地层为上石炭统本溪组含铁铝质页岩建造。已知矿体的形态、规模严格受奥陶纪—石炭纪之间的侵蚀间断面控制,属于古风化壳沉积型铝土矿。查明奥陶纪—石炭纪之间的侵蚀间断面形态及分布特征,对寻找深部铝土矿体有着十分重要的意义。

| Abstract: | Bauxite deposits known in Shaanxi Province are mainly distributed in Fugu County, Hancheng, Tongchuan and Baishui counties of Northern Shaanxi province. The ore-bearing rocks are composed of iron-bearing aluminous shale formation in the Benxi Formation of the Upper Carboniferous. The known shapes and sizes of bauxite ore bodies are strictly controlled by erosion of discontinuity between Ordovician and Carboniferous, belonging to Palaeoweathering crust-sedimentary type bauxite deposit. Understanding the pattern and distribution features of the erosion discontinuity would be significant to prospecting bauxite at depth. |
