摘要
本文阐述了下二叠统底部马鞍组含煤建造中的硬质高岭土矿的地质特征、物质成分、分布规律和成矿控制的因素。通过研究表明,矿石具有高铝低硅、低铁高钛,高岭石矿物含量高达85％以上,质量纯净,结晶程度好等特点,属无天然塑性、致密坚硬的硬质高岭土类型。有一定开发前景。
This paper describes the geological features, material components, distributional pattern, and controlling factors of mineralization of the hard kaolin deposit in the Maan coal formation at the bottom of the Lower Permian Series. It is shown that the ores are high in Al and Ti but low in Si and Fe, pure in quality with over 85％ kaolinite minerals, and good in crystallization. Therefore, they belong to the type of hard kaolin that is compact and hard without natural plasticity, and the deposit is, to some extent, perspective for exploitation.
