Abstract

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.
