摘要:
江西乐平涌山金矿点位于钦杭成矿带东段北部山门—涌山金多金属矿成矿远景区南东部,是最近新发现的金矿点。在野外地质调查和室内综合研究的基础上,对该金矿点的控矿特征进行研究,探讨自西向东横贯矿区的NE-NEE向韧性剪切带与金矿成矿的关系,总结成矿要素,并结合土壤地球化学异常特征分析其找矿远景。乐平涌山金矿点赋存于韧性变形明显的新元古代万年岩群浅变质岩地层中,呈脉状产出,NE向韧性剪切带是最主要的控矿导矿构造,万年岩群枫树岭组上段是赋矿围岩;矿床类型为韧性剪切构造蚀变岩型金矿。乐平涌山NE向韧性剪切带具有较好的找矿远景,该金矿点的发现为在钦杭成矿带东段北部寻找金矿提供了新思路,可进一步扩大该区找矿空间。
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 indoor 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.
