广东省阳山县深坑矿区石寨矿点成矿潜力分析

Analysis on Metallogenic Potential of Shizhai Ore Deposit in Shenkeng Mining Area,Yangshan County,Guangdong Province

深坑矿区石寨矿点自上世纪60年代以来,开展了较系统地质矿产勘查工作,前人认为该矿点铜多金属矿体矿化类型为构造裂隙充填型,矿化普遍,但矿体连续性差、规模小,表现出有“矿”无“体”之特征。本文从矿区地质背景入手,对石寨矿点的成矿条件进行了分析,着重对其矿化蚀变特征及原因等方面进行阐述,并对比国内主要矽卡岩型铜多金属矿床基本特征,提出石寨矿点具有寻矽卡岩型铜多金属矿床的潜力。

Since the 1960s,Shizhai Mine Site in Shenkeng Mining Area has carried out comparative exploration of systematic geological minerals.Previously,the mineralization type of copper polymetallic ore bodies in this mine site was structural fracture filling type,mineralization is common,but the mine poor continuity and small scale show the characteristics of"mine"without"body".Based on the geological background of the mining area,this paper analyzes the metallogenic conditions of the Shizhai ore deposit,and focuses on the characteristics and causes of mineralization and alteration,and compares the basic characteristics of the main skarn type copper polymetallic deposits in China.It is proposed that the Shizhai site has the potential to find skarn-type copper polymetallic deposits.
