摘要
本文是对广西合浦十字路风化壳型刮刀涂布高岭土勘查资料的总结,阐明矿床地质特征,成矿地质条件。认为该矿床是由那车洞花岗岩体风化残积而形成,成矿时代属于后晚第三纪。矿石的可选性能及其应用研究成果表明,矿区Ⅰ级品矿石为优质高岭土。主产品达到了造纸刮刀涂料的要求,并可得到造纸填料、日用陶瓷、玻璃原料等多种付产品,矿石的综合利用率高。根据成矿地质条件和找矿标志分析,指明地处褶断带构造中的钾长花岗岩分布位置,是该类矿床的找矿方向。
Based on the sum-up of the exploration data of the weathering-crust type coating kaolin deposits, this paper has clarified the geological characteristics of the deposit and its metallogenic geological conditions. It is believed that the dcposit is the weathered eluvial products of the Nachedong granite mass, its metallogenic age is Tertiary-Quaternary period. The separability of ores and its research result of application reveal that the I-grade ore in the mine is high-quality kaolinites. The principal products are up to the demand of papermaking coating material, and multiple by-products such as papermaking filling, daily ceramics, raw material for glass, etc. are got out of them, the comprehensive utilization ratio of ore is high. On the basis of the analyses on the metallogenic geological conditions and the guides of prospecting ore, the paper has pointed out that the potash feldspar granite distributed in the fold-fault belt is the prospect of exploration.
