我国是世界上一水硬铝石型铝土矿储量最多的国家.因而研究该类型矿床成矿理论有着重要意义.作者对豫、晋、桂、黔、鲁和滇等省(区)的主要铝土矿床的成因进行了研究,获得了一些粗浅的认识. 矿床地质概况我国主要铝土矿床,均分布在东部准地台范围内古陆边缘的灰岩侵蚀面上.成矿时代和含矿岩系见表1.矿体为层状、似层状、透镜状和囊状,厚0.2～35米.矿床的产状、形态、厚度、品位取决于底板灰岩侵蚀面的形态特征(广西平果
China is the country with the most diaspore bauxite reserves in the world, so it is of great significance to study the mineralization theory of this type of deposit. The origin of bauxite deposit has been studied and some superficial knowledge has been obtained.General overview of deposit Geology The major bauxite deposits in our country are distributed on the limestone erosion surface of the continental margin within the quasi-platform area of the eastern part of China. The ore-bearing rock series are shown in Table 1. The ore body is stratified, stratified, lenticular and cystic, with a thickness of 0.2-35 meters.The shape, thickness, and grade of the deposit depend on the morphological characteristics of the limestone erosion surface (Guangxi Pingguo
