| 摘 要： | 罗甸滑石矿是贵州首次发现的白滑石矿,矿体呈似层状、透镜状产于辉绿岩体与围岩的接触带内,与罗甸玉共生。罗甸滑石为低铝、低铁质矿石,MgO含量接近滑石的理论值,结晶细、质纯、白度高,具有较高的开发利用价值,填补了贵州没有优质滑石矿的空白。罗甸滑石矿与罗甸玉矿的地质背景及其空间产出部位相同,并且具有相似的稀土元素组成及配分模式,揭示二者为相同成因,属于接触交代型矿床。

| Abstract: | Luodian talc ore is the white talc ore first found in Guizhou, the ore bodies are bedded and lenticular occurs in the contact zone between the diabase body and the surrounding rock, belong to the paragenetic minerals of Luodian nephrite. Luodian talc ore is low alumina and low iron, that the MgO content is close to the theoretical value of talc. Luodian talc ore with its fine crystal, pure quality and high whiteness, has high exploitation value. It fills the void that there is no talc ore of high quality in Guizhou before. Luodian talc deposit and Luodian nephrite deposit have same geological background and formed position as well as similar REE composition and pattern. It shows that these two deposits possess same genesis, which is contact metasomatic deposit. |
