摘  要:介绍了滑石矿资源储量、分布、消费情况,简述了滑石矿床成因类型划分方案,我国滑石矿床类型的矿床特征和矿石质量、矿石加工技术性能、工业利用,探讨了矿床类型划分存在问题。通过对我国滑石矿床成矿条件、成矿作用和矿床特征归纳总结,结合矿床工业价值,遵循我国滑石矿床成因、分类从简和与已有矿床类型可类比原则,提出我国滑石矿床工业类型划分为变碳酸盐岩型矿床、沉积改造型矿床、接触交代型矿床、岩浆岩自变型矿床和风化残积型矿床等5种类型,简述了典型矿床特征。矿床工业类型划分是对以往勘查工作的总结,有利于指导滑石矿产勘查评价和促进矿产开发工作。The reserves,distribution and consumption of talc mine resources are introduced,with a briefl description of the classification of genetic types of talc deposits,The geological characteristics of ore quality,technical performance of processing,and industrial utilization of talc deposits in China are summarized.The classification of talc deposits are further discussed.By summarizing the metallogenic conditions,mineralization,deposit characteristics and industrial value of the talc deposits in China,in combination with the principles of simplicity and comparability,five different commercial types of talc deposits in China are proposed in this study.They are metacarbonate talc deposits,sedimentary transformed talc deposits,contact metasomatic talc deposits,magmatic autometamorphic talc deposits,and weathered residual talc deposits.The characteristics of typical deposits of the five different types of deposits are briefly described.The proposed classification of industrial types of mineral deposits presents a summary of previous exploration experience,with a guiding in the exploration and evaluation of talc development.
