Geological Characteristics and Genesis Analysis of Tianjingshan Gold Deposit in Xiuning County
摘要
Abstract
Tianjingshan gold deposit is located in the south of Xiuning county,Anhui province,which is a typical tectonically altered rock type gold deposit in the Huangshan-Xiuning metallogenic belt in the western section of the Jiangnan orogenic belt.This paper conducts a systematic study on the geological conditions,petrology,mineralogy of ores,and fluid inclusions in the mining area.Combined with the analysis of the regional geological background,it is concluded that the mineralization process of Tianjingshan gold deposit is closely related to the granitic magma activity during the late Yanshan period.Gold is mainly found in quartz veins and alteration zones,coexisting with pyrite and arsenopyrite,exhibiting obvious characteristics of structure-alteration-mineralization integration.The formation of Tianjingshan gold deposit is controlled by regional fault zones and belongs to the tectonic alteration rock type hydrothermal gold deposit,and the mineralization process has gone through two stages,namely the quartz-pyrite-gold stage and the quartz-carbonate-chlorite stage.The study of this deposit not only reveals the mineralization laws of gold deposits in Southern Anhui,but also provides important references for the understanding of the tectonic magmatic mineralization system in the Jiangnan orogenic belt.关键词
