湖南省桂阳县杨柳矿区玻璃用石英岩矿矿床特征及成因浅析

本文以桂阳县杨柳矿区玻璃用石英岩矿为研究对象,通过对杨柳矿区区域地质背景、矿区地质概况、矿床地质特征和矿床成因的研究分析,认为矿区矿床类型为岩浆热液充填交代型矿床。矿区位于塔山岩体西南缘,塔山岩体为矿体的形成提供了热源;区域断层塔山断裂往北东切穿岩体,为矿体的形成提供了导矿及容矿空间;石英岩矿产于北东向断裂中,呈似层状、脉状、透镜状产出,总体产状严格受断裂控制。

Characteristics and Genesis of Quartz Ore Deposit for Glass in Yangliu Mining Area,Guiyang County,Hunan Province

This paper takes the quartzite ore for glass in Yangliu mining area of Guiyang County as the research object,Based on the analysis and study of the regional geology of Yangliu mining area,it is considered that the deposit is of magmatic hydrothermal filling metasomatic type.The mining area is located in the southwest edge of Tashan rock mass,which provides the heat source for the formation of the ore body;the regional fault Tashan fault cuts through the rock mass to the northeast,which provides the ore guiding and ore containing space for the formation of the ore body;the quartzite mineral is in the northeast fault,which is layered,veined and lenticular,and the overall occurrence is strictly controlled by the fault.
