HISTORIC-DYNAMIC ANALYSIS OF GOLD METALLOGENY OF WEST SARAWAK,EAST MALAYSIS
作者：YANG Mu PENG Sheng-lin
摘要：West Sarawak,which located in the northwest of South Kalimantan Diwa Region,underwent geosynclinal period (An C-T),platform period (J1-J2) and diwa period (J3-).In geosynclinal evolution period,the crust was thickened and accreted by sedimentary accumulating,orogenic movement and metamorphism.In the different kinds of volcanic-sedimentary rocks,content of gold is general higher than the mean value of upper crust and its enrichment factor ranges from 0.94 to 4.7.The basement tectonics formed in geosynclinal fold inversionstage strike northeast,which controlled the distribution ofmagmatic activities and gold mineralization belts of the west part of west Sarawak.
