广西五圩矿田箭猪坡矿床构造变形及演化
Tectonic Deformation and Evolution of the Jianzhupo Deposit in Wuxu Ore Field,Guangxi
摘要
Abstract
Based the research of the tectonic deformation and evolution period of the Jianzhupo deposit,we discuss the tectonic geometry,kinematics and dynamic characteristics of the mining area,to study the controlling effect of tectonic evolution on mineralization.The Jianzhupo deposit area has developed folds,faults and joints,and is characterized by multi-stage activities.The folds contain upright dipping folds and oblique dipping folds,and the axial direction is NW,NE and NS.The faults and joints can be divided into five groups according to the trend:NE,NW,NNW,NS,and EW,and the order of fault formation is NW,NNW→NE→EW→NS,and the joints are mainly sheared joints.There are four main compressive stresses in the study area:NE-SW,NW-SE,EW and NS(NNW).The tectonic evolution of the study area is comprise of four periods,with D2 and D3(middle and late Yanshan)being the main metallogenic periods.The lateral direction of NNW to the tensile torsional fault and the intersection with the NW fault have good prospecting prospects.关键词
