江西乐平涌山地区韧性剪切带对金矿化的控制及找矿远景
Control effect of ductile shear zone on gold mineralization and its ore-searching prospects in Yongshan area,Leping City,Jiangxi Province
摘要
Abstract
The newly discovered Yongshan gold deposit in Leping City,Jiangxi Province is located in the southeastern Shanmen-Yongshan Au polymetallic metallogenic prospect area,belonging to the northern part of eastern Qinzhou-Hangzhou Metallogenic Belt.According to field geological survey and in-door comprehensive research,the ore-controlling characteristics of Yongshan gold deposit in Leping City were studied with the discussion of the relationship between the NE-NEE-trending ductile shear zone across the mine from west to east and gold mineralization.This paper summarized ore-forming factors and analyzed its ore-searching prospects based on the characteristics of soil geochemical anomalies.The results show that the Yongshan gold deposit occurs in the Neoproterozoic shallow metamorphic rock strata with obvious ductile deformation,the NE-trending ductile shear zone is the main ore-controlling and ore-guiding structure,and the upper member of Fengshuling Formation is the ore-bearing wall rock.The Yongshan gold deposit is determined as ductile shear tectonic-altered rock type and its NE-trending ductile shear zone has a good ore-searching prospects.The discovery of this gold occurrence provides a new thought to the gold searching in the northern part of eastern Qinhang Metallogenic Belt,expanding the prospecting space in this area.关键词
