遵义仙人岩铝土矿矿物学特征研究

摘要

This paper deals with mineralogy of diaspore, illite, kaolinite, chlorite, hematite and pyrite from the Xianrenyan bauxite deposit in Zunyi, Guizhou based on thin section observation, differential thermal and EMP analyses, SEM and so on. The study indicates that the Xianrenyan bauxite deposit may be correlated to the Zibo bauxite deposit in Shandong.%应用矿石薄片、重砂鉴定与扫描电镜、电子探针和X射线衍射分析等对遵义仙人岩铝土矿的矿物成分进行了研究，论述了硬水铝石与伊利石、高岭石、绿泥石、赤铁矿以及黄铁矿等的矿物学特征，包括其结晶形态、粒度、物理光学性质和产出特征等；阐明了主要矿物在不同工业类型矿石中的含量及其组合特征。遵义仙人岩铝土矿与山东淄博“G 层”铝土矿类比，矿物成分大同小异，均属“一水硬铝石（硬水铝石）型沉积铝土矿床”。
