| 摘 要： | 为了了解江西省上饶市广丰区黑滑石矿石矿物特征、地球化学特征及碳含量特征等，以便更好地利用黑滑石，助力打造黑滑石百亿元产业基地，通过对该区黑滑石开展野外调查、岩相学、地球化学分析等，并在此基础上提出对黑滑石应用的建议。结果显示本区黑滑石矿石类型主要为假鲕状滑石岩、角砾状滑石岩、片理化滑石岩等。矿石中矿物主要为黑滑石、石英及白云石，化学成分主要为SiO2、MgO和CaO；假鲕状滑石岩和角砾状滑石岩的总碳和无机碳含量明显低于片理化滑石岩，而有机碳含量明显高于片理化滑石岩；本区黑滑石初步达到塑料、陶瓷、橡胶及涂料用滑石一级标准。

| Abstract: | In order to understand the mineral characteristics, geochemical characteristics and carbon content characteristics of black talc ore in Guangfeng District, Shangrao City, Jiangxi Province, make better use of black talc and help to build a 10 billion yuan industrial base of black talc.Based on the field investigation, petrography and geochemical analysis, some suggestions on the application of black talc are put forward.The results show that the main types of black talc in this area are pseudooolitic, brecciated and schistose talc.The main minerals in the ore are black talc, quartz and dolomite.The chemical composition of the ore is mainly SiO2, MgO and CaO.The contents of total carbon and inorganic carbon in pseudooolitic and brecciated talc are significantly lower than those in schistose talc.But the content of organic carbon is higher than that of schistose talc.The black talc in this area has preliminary reached the first grade standard of talc for plastics, ceramics, rubber and coatings. |
