Typical ore deposit spots in Tuanyuan silver poly-metallic ore assembly area in southwest of He'nan Province: evidence from ore geology, fluid characteristics and zircon U-Pb dating
摘要
Abstract
Tuanyuan silver poly-metallic ore assembly area is located at central qinling orogenic belt in southwest of Henan province. Many metallic ore deposit distributed in this area, such as Banchang copper poly-metallic deposit, Yindonggou silver poly-metallic deposit, Xuyaogou gold deposit and Yinhuman lead-zinc poly-metallic deposit, at the same time, some of gold-silver ore-spots also located at this area such as Wanrendonggou, Tieluogou and Wangou. Research about fluid inclusion demonstrated that complex types of fluid inclusions in quartz veins always related with ore-forming process, especially in abundance of gas-rich fluid inclusion, and barren quartz veins always had simple type of fluid inclusions such as NaCl-H2O. Through Zircon 206Pb/238U dating research of Luji aping and Wulongtan granite the earliest ore forming time can be presumed to Caledonian. Systematically research of ore-deposits and ore-spots in Tuanyuan silver poly-metallic ore assembly area,ore deposit in this area can be classified as three types.①VMS and SEDEX deposit related with stratum, volcanism supplied ore-forming materials and later hydrothermal superimposition to form ore deposit, Yinhuman lead-zinc poly-metallic deposit as an example; ②Alteration and quartz vein type of gold-silver poly-metallic deposit related with structure process, ore -forming materials origined from depth and stratum,and Zhuyangguan-Xiaguan sub -fracture belts supplied the ore-control space, Yindonggou silver poly-metallic deposit as an example; ③Porphyry and skam deposit related with neutral to acid intrusions, ore-forming materials origined from depth and stratum, and Zhuyangguan-Xiaguan fracture belt supplied the ore-control space, Banchang copper poly-metallic deposit as an example.关键词
