湖南湘西北地区东山峰滑石矿床地质特征及成因概述

Geological features and genesis of the Dongshanfeng talc deposit in northwestern Hunan Province

滑石矿是一种重要的非金属黏土矿物材料,被广泛应用于陶瓷、造纸、涂料、塑料、橡胶、医疗、化妆品等制造行业。本文对湖南湘西北地区东山峰滑石矿床的区域地质背景、矿区地质概况和矿床地质特征进行了详细分析,探讨了其矿床成因。认为该滑石矿地质成因为自生沉积-动力变质改造成因模式,矿床类型为沉积-动力变质碳酸盐型滑石矿床。

Talcum is an important non-metallic clay mineral material,which is widely used in ceramic,paper,paint,plastic,rubber,medical,cosmetics and other manufacturing industries.This paper made a detailed analysis of the regional geological background,general situation and geological features of Dongshanfeng talc deposit in the northwest of Hunan Province,and discussed the genesis of the deposit.It was considered that the geological genesis of talc was due to the genetic model of authigenic sedimentation-dynamic metamorphism.The deposit type is sedimentary dynamic metamorphic carbonate type talc deposit.
