中文摘要:
      洪水河锰矿位于东昆仑东端,大地构造位置上属秦祁昆造山系东昆仑弧盆系—北昆仑岩浆弧,北接柴达木地块,在成矿带的划分上属伯喀里克—香日德金-铅-锌-钼—石墨—萤石(Cu 、稀有、稀土)成矿带。作者通过3年工作发现2条锰矿带,圈出锰矿体7条。在对洪水河锰矿床地质特征研究基础上,查明了锰矿成矿地质条件、控矿因素,成因属于沉积变质型,并建立了东昆仑成矿带沉积变质型锰矿床地质—地球物理找矿模型,确定中元古界狼牙山组为东昆仑锰矿重要含矿层位。
英文摘要:
      Hongshuihe manganese deposit is located in the east end of Eastern Kunlun, where tectonically belongs to areas along Eastern Kunlun arc-basin system-Northern Kunlun magmatic arc of Qinling-Qilianshan-Kunlun Orogenic system, neighboring Qaidam terrane to the north. In terms of metallogenic belt, it belongs to Bokalike-Xiangride Au-Pb-Zn-Mo-Graphite-Fluorite (Cu, rare and rare earth) metallogenic belt. The author has found two manganese metallogenic belts and delineated seven manganese orebodies during three years exploration works. Based on the study of geological characteristics of Hongshuihe manganese deposit, the metallogenic geological conditions and ore controlling factors of manganese deposit have been surveyed. It has been found that the genesis of deposits belongs to sedimentary metamorphic type. A geological geophysical prospecting model has been developed for the sedimentary metamorphic manganese deposit in the Eastern Kunlun metallogenic belt in this paper, through which Mesoproterozoic Langyashan formation has been identified as the important ore-bearing strata for manganese deposit in Eastern Kunlun.
