摘　　要：对扒村铝土矿进行现场调查和室内综合研究,从区域成矿背景、矿床地质特征、矿石质量及矿石成分、矿石物质来源、成矿环境等角度分析扒村铝土矿的矿床成因、成矿机制及成矿模式,认为该矿床主要赋存于石炭系上统本溪组,属近海湖泊相胶体化学沉积型矿床。研究成果可为今后在华北准地台地区寻找石炭系上统本溪组富矿层铝土矿提供线索和思路。Based on the synthetic studies both in field and laboratory of bauxite in Bacun of Yuzhou City in Henan Province,this paper analyzes the metallogenetic environment and mineralization,metallogenic mechanism and metallogenic model of the ore from the perspectives of regional background,geological features,quality,composition,genesis and the ore-forming environments.The comparative analysis shows that this ore mainly occurs in the Upper Carboniferous Benxi Formation of the Ordos Basin and belongs to lacustrine colloidal deposit.The research results can give insights into the searching of bauxite in the Upper Carboniferous Benxi Formation in the paraplatform of North China.

关 键 词：湖泊相胶体沉积 本溪组含矿岩系 扒村铝土矿 矿床成因 成矿模式
