Ore-controlling structure and exploration target of Xiejiagou gold deposit in northwest Jiaodong area
摘要
Abstract
Xiejiagou gold deposit is located on the branch rupture of the Zhaoping fault in northwest Jiaodong and has been a member of crisis mines.The study on the structural ore-controlling rules of the Xiejiagou gold deposit is of great significance to its deep and peripheral ore exploration.The metallogenic tectonic system of the mining area is reconstructed,based on structural geological survey,measurement and statistics of the attitudes of the ore veins and vein rocks,and analysis results of rocks and ores and isotopic geochemistry data.The evolutionary sequence of metallogenic structure can be divided into three phases:pre-mineralization,mineralization,and post-mineralization.The structural ore-controlling rules of the deposit can be described as follows:the strike of the ore body is obviously controlled by NNE orientation fault;the pitch of the ore bodies are from SW to NE;the vein group is distributed in echelon and formed by sinistral shear and has obvious mineralized centers;and the mineralized zones are consistent with the tectonic alteration zones.This paper proposes two target areas and provides reference for future ore exploration.关键词
