中文摘要:
      万全寺银金矿床位于张宣幔枝构造东侧的侏罗纪断陷盆地中,成矿时限晚于133.33Ma~101.82 Ma.通过硫、铅、氢、氧、碳及稀有气体同位素研究认为,成矿物质应源自地球深部,在中生代冀西北幔枝构造演化过程中集中成矿.成矿热液以岩浆水为主并加入了部分天水.
英文摘要:
      Wanquansi Ag- Au deposit is located in the Jurassic fault depression at the east part of Zhangiiakou -Xuanhua mantle branch structure. Ag- Au mineralization is posterior to 101.82 to 133.33 Ma. Based on sulfur, lead, oxygen, carbon and noble gases isotopes, it is considered that the mineralizing materials came from the deep mantle. Economic ores were concentrated in the process of mantle branch evolution during Mesozoic. Hydrotherreal fluids were dominated by magmatic water with some meteoric water.
