| 摘 要： | 稳定同位素、岩石微量元素(金)和地质特征研究的结果,表明金场子金矿床的成矿物质来源系上地壳源,并且金、银、铅、铜等金属和硫、硒、砷、氯、氟、碳等来源于石炭纪和泥盆纪沉积岩。成矿流体是大气水和沉积地层水的混合溶液。金矿化与地热流体渗流热卤水成矿作用和表生风化成矿作用有关。

| Abstract: | The results of investigation of stable isotope, minor element(gold ) of rocks and geological characteristics indicate that the source of mineralized material of gold deposit from Jinchangzi in Ningxia comes from the upper crust, and gold,silver, lead, copper etc.and surphur, selenium, arsenic, chlorine, fluorine etc. take its source at Carboniferous and Devonian sedimentary rocks. The ore -forming fluid is a mixed solution of the atmospheric water and sedimentary stratal water. Gold mineralization is related to metallogeneses of transmis-sive hot brine geothermal fluid and of supergene weathering. |
