Abstract:Abstract:Hu Jiashan area is located in eastern of Yongping deposit in Yanshan County, Jiangxi province, which is new major breakthrough of geological prospecting in last years and increased about 300,000 tons Cu resource of 333+334 type. Taking the Hu Jiashan drilling ZK725 as the main research object, we found two kinds of mineraliation genesis in shallow part where above 766.0m depth in drilling ZK725 and deep part under 766.0m based on collected samples, indoor petrologic and mineralogical determination, SEM and EDS analysis. The shallow part is magmatic hydrothermal-structure mineralization and the deep part is the eastern extension of Yongping deposit. (Zn, Sb) Tetrahedrite in quartz vein type ores represented the signs of hydrothermal mineralization, mylonite magmatite reflected structure mineralization. The presence of a large number of colloidal pyrite means that there had been large-scale hot water sedimentary and the same mineralization system as Yongping deposit. We also have found (Zn, Sb)Tetrahedrite, Re-scheelite, Re-ferberite, uraninite, thorianite, pilsenite, hammarite, hessite, volynskite. In addition to copper, zinc, lead, cadmium and tungsten, we made sure the concentration of bismuth and indium up to the lowest level for exploration.
