| 摘 要： | 蒙甘新相邻(北山)地区地处塔里木、哈萨克斯坦-北山和西伯利亚板块交汇处,区内深大断裂纵横交错,各类岩浆岩分布广泛,金属矿床(点)星罗棋布,是我国北方最重要的金属矿化集中区之一.近几年来,随着该区矿产地质调查工作的全面开展,本区金属矿床理论研究和找矿勘查均获重要进展,特别是白山铼(钼)矿床和流沙山金(钼)矿床的发现与厘定,致使本区再度成为国内外矿床地质学家关注的"热点”.认真研究和分析上述2种新类型矿床的产出环境和地质特征,不仅有助于贵重金属矿床形成过程的了解,而且对在北山海西期岩浆岩发育区进一步寻找新类型贵重金属矿床具有重要指导意义.

| Abstract: | Located in the convergence area of Siberian, Kazakhstanian-Beishan and Tarim paleo-plates, the Inner Mongolia-Gansu-Xinjiang juncture area (Beishan) is one of the most important metallogenic provinces in China. Deep-seated faults, Paleozoic igneous rocks and precious metal deposits (spots) are well developed in this area due to the multiphase Paleozoic events. Recently, systematic geological investigations on the mineral resources of this area have made a breakthrough both in basic theoretic studies and mineral exploration of the precious metal deposits. Most of these precious metal deposits show an intimate relationship with the Hercynian tectonism and magmatism. Among these deposits, the Beishan Re(Mo) and the Liushashan Au(Mo) deposits discovered in 1996 and 1999 have attracted the attention of geologists both at home and abroad. An integrated analysis of the geological setting as well as geological and geochemical features of these two deposits will greatly upgrade the understanding of the ore-forming processes of the Re (Mo) and Au (Mo) deposits. Meanwhile, the genetic model and mineral exploration criteria of these two unique precious metal deposits can also be used to make comprehensive evaluation of the concealed precious metal deposits in the Inner Mongolia-Gansu-Xinjiang juncture (Beishan) area. |
