Analysis on Metallogenic Regularity of Copper-Polymetallic Deposits in Hengyang Basin and its Periphery
摘要
Abstract
The geotectonics of the Hengyang basin is located in the west segment of the Qinzhou-Hangzhou metallogenic belt where between the south China plate and the Yangtze plate,it belongs to the intersection area between the middle part of the Qinzhou-Hangzhou metallogenic belt and the north edge of the east-west tectonic-magmatic-metallogenic belt in middle Nanling mountains.The paper studied on geological features of Hengyang basin,tectonic evolution and magmatic hydrothermal activity,metallogenic age,spatial distribution characteristics of copper-polymetallic deposits,and the results show the mineral resources in the basin and its periphery are characterized by long period,multiple mineral species and strong enrichment.Different tectonic units and evolutionary stages control different ore-bearing formations,temporal and spatial distribution rules of mineralization and paragenetic association of deposits in the basin.By examining the relationship between plate tectonic e-volution stage and copper-polymetallic mineralization distribution in space-time as well as their sepuence,it summarizes a new metallogenic regularity of copper-polymetallic mineral-ization in the area.The metallogenic regularity shows that the copper-polymetallic metallo-genic types related to tectono-magmatic intrusions in the area has the characteristics of hor-izontal and vertical zoning from the rock mass to outwards such as intralesional type W-Sn-Cu-U-albite deposit→rock mass exocontact type U-Cu-Pb-Zn-W-Fe deposit→skarn type Fe-Cu-Pb-Zn(Au)deposit→filling metasomatic type Cu-Pb-Zn-barite-fluorite deposit.关键词
