摘要
本文在概述了国内外学者关于铝土矿矿床成因类型划分沿革之后,主要对贵州沉积类硬水铝石铝土矿矿床进行了初步的成因类型划分。根据铝土矿成矿时代、基底岩性、铝土矿合矿岩系剖面特征、主要矿石工业类型及成矿环境等认为,贵州铝土矿均属沉积类,其下划分为两个亚类和五个类型,即猫场型、后槽型、仙人岩型、凤王槽型和大竹园型。文中详细列举了11个剖面的岩性及化学成分资料。本文仅供有关部门今后对我国铝土矿矿床进行全面、系统地成因分类时参考。
Based on metallogenetic epoch. lithology of basement rocks,geologic features of ore-bearing rock unit showed on cross-sections, anddeposition envrionment, in combination of industry tyoe of ores, the ban-cite oredeposits in Guizhou should be divided into genetically sedimentary type with twosubordinate types and futher subdivided into five types of the Maochang,Houcao,Xianreyan, Fengwangcao, and Dazhuyuan. The informations on lithology andchemical compostions of the bauxite deposits summarized from 11 explorationsections are offered in this paper for the reference in the genesis-typeclassification of ban-cites in China.
