摘要
本次研究的中蒙俄跨境区在大地构造位置上位于中亚造山带东部,是多种矿产的成矿密集区。本区成矿区带包括2个Ⅰ级成矿域、2个Ⅱ级成矿省和9个Ⅲ级成矿带。区内金属矿床的分布主要受北东-北北东向及北西向两组断裂的控制。研究区重点金属矿产中,铜矿床以斑岩型为主;金矿床以岩浆热液型为主,也有部分作为伴生矿种产于斑岩型铜(金)矿床之中;铅、锌矿床以热液脉型为主;铀矿床以火山岩型为主。铜、金、铅、锌、铀成矿作用与燕山期岩浆及其热液活动关系最为密切。本研究区具有良好的成矿地质条件和巨大的找矿前景,是进一步开展铜、金、铅、锌、铀等金属矿产找矿工作的重点地区。
The cross border area of China,Mongolia and Russia in this study is located in the eastern part of Central Asian orogeni belt,which hosts massive multiple mineral resources.The mineralization belts in the study area include two giant metallogenic regions of class Ⅰ,two metallogenic provinces of class Ⅱ,and nine metallogenic belts of class Ⅲ.The distribution of nonferrous metal mineral deposits is mainly controlled by two sets of faults trending in NE-NNE and NW.The major types of copper,gold,lead-zinc,and uranium deposits in the study area are porphyry type,magmatic hydrothermal type(with some gold formed in some porphyry type copper(gold)deposits as associated mineral),hydrothermal vein type,and volcanic type,respectively.The metallogenesis of copper,gold,lead-zinc,and uranium deposits were closely related with the magmatism and hydrothermal processes in the Yanshanian period.This area has good metallogenic conditions and great prospecting potential.Therefore,the study area is a focused district to launch further prospecting of nonferrous metal mineral resources such as copper,gold,lead,zinc,and uranium.
