Influence of Structure on Mineralization in Qingchengzi Lead-zinc Deposit Area
This paper systematically analyzes the ore-controlling structure of Qingchengzi ore concentration area in eastern Liaoning province.The tectonic conditions for the lead-zinc deposit ore body are studied by using gravity inversion method,and the indication significance of oreprospecting also be summarized.The research shows that the distribution of the deposit is closely related to the rock mass morphology and emplacement,which is mainly controlled by the fault structure.In this region,Shuangdinggou and Xinling granite which formed in Indosinian period occur as lopoliths and connect at depth.The Indosinian rock mass formed an advantageous environment for lead-zinc mineralization,while fault structure provides a migration pathway for ore-forming hydrothermal fluids.The contact zone between rock mass and surrounding rock,interlayer fracture zone and interlayer fault are the most important location of ore prospecting in Qingchengzi ore concentration area.
