重晶石矿自然重砂矿物组合规律及其找矿意义

摘要

Based on natural heavy minerals data, the authors mainly studied statistics of frequencies of occurrence of natural heavy minerals from different types of typical barite deposits. The results show that two major barite deposit types have representative natu⁃ral heavy minerals, i.e., barite+pyrite+limonite in sedimentary type deposits and barite+lead group minerals+chalcopyrite+fluo⁃rite+pyrite+sphalerite+stibnite+malachite in hydrothermal vein type deposits. Further interpretations were made based on these results, which can provide important geological information for the study of ore genesis and exploration.%在丰富的自然重砂数据资料基础上，对全国各省37个典型重晶石矿床中的自然重砂矿物报出结果进行了相关研究，发现2种成因类型的重晶石矿床具有特定的自然重砂矿物组合，沉积型重晶石矿床的自然重砂矿物组合为重晶石+黄铁矿+褐铁矿，热液型自然重砂矿物组合为重晶石+铅族矿物+黄铜矿+萤石+黄铁矿+闪锌矿+辉锑矿+孔雀石。同时，对此特征性自然重砂矿物组合进行了相关分析，为重晶石的找矿矿物学发展提出相关建议。
