【摘要】 通过总结中蒙俄经济走廊产出的198个大型-超大型(或代表性)矿床的产出环境、地质特征和矿产类型,以及走廊腹地矿产资源的分布规律和找矿潜力认为,中蒙俄经济走廊可划分为中朝成矿段、乌拉尔-蒙古成矿段、西伯利亚成矿段和欧洲成矿段。其中,中朝和乌拉尔-蒙古成矿段以产出大型-超大型铜-金、银、铅锌和锡矿床为特征,欧洲段以镍-铜、铁、金和铅-锌矿床(点)为特征,西伯利亚成矿段则以富产镍-铜-铂族元素和铌多金属及金刚石矿床为特征。太古宙—新生代,该区不同构造单元经历了6次主要的构造演化及成矿时期,主要有前寒武纪的BIF型铁矿、加里东期的斑岩型铜-金、岩浆型钒钛磁铁矿和古老与侵入体有关的热液脉型金矿、华力西期的钨-锡多金属矿化、中生代金、银-铅-锌、钨锡等多金属的成矿大爆发、新生代岩浆热液矿床。走廊中东部优势矿种为铜、钼、金、银、铅-锌和金刚石,主攻矿床类型为斑岩型、热液脉型、低硫化浅成低温热液型、冲积型、海相火山岩型;西部优势矿种则为铁-铜、镍-铜、铅-锌,主攻矿床为IOCG型、斑岩型和热液脉型。更多还原

【Abstract】 The purpose of this study is to enhance the knowledge of the distribution and acquire information on research and exploration of ore resources in the hinterland of the corridor.Preliminary study shows that China-Mongolia-Russia Economic Corridor can be divided into four metallogenic zones: Sino-Korea metallogenic zone,Ural-Mongolian metallogenic zone,Siberian metallogenic zone and European metallogenic zone.Among them,the Sino-Korean and Ural-Mongolian metallogenic belts are characterized by wide distribution of large-scale Cu-Au,Ag,Pb-Zn and Sn-polymetallic deposits, the European metallogenic zone is characterized by enrichment of Ni-Cu,Fe,Au and Pb-Zn deposits,and the Siberian metallogenic sections are characterized by wide distribution of the Ni-Cu-PGE,Nb-polymetalland diamond deposits.A study of ore-forming pedigree shows that the different tectonic units in this region mainly underwent six stages of crust evolution from the Archaean to the Cenozoic,corresponding to six periods of ore deposits:the TIF-type Fe-deposits formed in Precambrian,the porphyry Cu-Au and magmatic Vi-bearing titanomagnetite deposits formed in Caledonian,the hydrothermal vein-type Au deposits related to the intrusions,Sn-polymetal mineralization,Au,Ag-Pb-Zn,Sn-W and other polymetallic deposits formed in Yanshannian period and some hydrothermal deposits formed in Cenozoic.Main ore species in eastern and central part of the corridor are Cu,Mo,Au,Ag,Pb,Zn and diamond.The main types of deposits are porphyry,hydrothermal vein,LS epithermal,alluvial,and marine volcanic rock types,and main ore species in the western part of the corridor are Fe-Cu,NiCu,Pb-Zn,with the main deposits being of IOCG,porphyry and hydrothermal vein types.更多还原
