江西省分宜县湖泽—凤阳一带镁质黏土矿矿床地质特征与找矿前景

Geological Characteristics and Prospecting Potential of Magnesium Clay Deposits in Huze-Fengyang Area,Fenyi County,Jiangxi Province

为了系统总结江西省分宜县湖泽—凤阳一带镁质黏土矿找矿成果,为区内镁质黏土找矿提供参考,以白路塘、失宝山、上山背、桂山4个地区为研究对象,调查了研究区基本地质特征,分析了镁质黏土矿分布范围、规模、产状和矿石质量等。结果表明:镁质黏土矿体多呈(似)层状产出,矿物成分以滑石、石英和方解石等为主;有益化学成分MgO平均含量为22.35%;矿石自然类型为滑石型镁质黏土,工业类型为陶瓷原料用镁质黏土矿;矿床成因类型为风化残积型。

In order to systematically summarize the prospecting results of magnesian clay deposits in the Huze-Fengyang area of Fenyi County,Jiangxi Province,and provide reference for the prospecting of magnesian clay deposits in the area,four areas of Bailutang,Shibaoshan,Shangshanbei and Guishan were taken as the research objects.The basic geological characteristics of the study area were investigated,and the distribution range,scale,occurrence and ore quality of magnesian clay deposits were analyzed.The re⁃sults show that the magnesian clay ore bodies are mostly(like)layered,and the mineral components are mainly talc,quartz and calcite.The average content of beneficial chemical composition MgO was 22.35%.The natural type of ore is talc-type magnesia clay,and the industrial type is magnesia clay ore for ceramic raw materials.The genetic type of the deposit is weathering residual type.
