俄罗斯地质背景及优势金属矿产分布规律

Geologic setting and principal metal mineral resources distribution regularities of Russian

  • 摘要:
    研究目的 俄罗斯矿产资源十分丰富,在全球矿业市场占有重要地位。新形势下,了解俄罗斯地质背景、矿床成因类型和地质特征等,对提升区域基础地质研究水平和促进中俄国际矿业合作具有重要意义。
    研究方法 本文对俄罗斯的地质背景进行了总结,并对优势金属矿产的空间分布、资源禀赋、成因类型、地质特征等进行了梳理。
    研究结果 研究区经历了古大陆岩石圈的裂解和拼合导致多期活化,为矿床形成奠定了物质基础,优势金属矿产有铂族、稀有金属、钛、金、铁、钨、锌、银、铅、铜、镍、锡、锆、钼等,其中铂族储量占全球37%。
    结论 俄罗斯矿产的形成具有时空专属性。太古宙—古元古代时期,形成BIFs矿床、硫化物型Cu–Ni–PGE矿床、砂岩型铜矿床。中元古代形成岩浆型铬铁矿和钛铁矿,大量矽卡岩型、伟晶岩型、热液型和喷流沉积型矿床。古生代—早中生代,形成岩浆型Fe–Ti–V矿床、喷流沉积型Cu–Zn–Au矿床、矽卡岩型Fe、Cu、W等多金属矿床、热液脉型Au矿床等、硫化物型Cu–Ni–PGE矿床。中生代成矿期主要矿床有热液脉、斑岩/矽卡岩型金、银、铜、钼、钨、锡等矿床(点)。

     

    Abstract:
    This paper is the result of geological survey engineering.
    Objective Russia is rich in mineral resources and occupies an important position in the global mining market. Under the new situation, understanding the geological background, genetic types and geological characteristics of mineral deposits in Russia is of great significance for improving the level of regional basic geological research and promoting the international mining cooperation between China and Russia.
    Methods This paper summarized the geological background of Russia, and sorted out the spatial distribution, resource endowments, genetic types, and geological characteristics of principal metal mineral resources.
    Results The study area has experienced multi-stage activation due to the cracking and splicing of the ancient continental lithosphere, which has laid a material foundation for the formation of ore deposits. The principal minerals include platinum group, rare metals, titanium, gold, iron, tungsten, zinc, silver, lead, copper, nickel, tin, zirconium, molybdenum, etc. Platinum group reserves account for 37% of the world.
    Conclusions The formation of Russian minerals is unique in time and space. During the Archean–PaleoProterozoic period, BIFs deposit, sulfide−type Cu−Ni−PGE deposit and sandstone type copper deposit were formed. In the Middle Proterozoic, magmatic chromite and ilmenite were formed, and a large number of skarn−type deposits, pegmatite deposits, hydrothermal deposits and Sedex deposits were formed. From the Paleozoic to the Early Mesozoic, magmatic type Fe−Ti−V deposit, sedex Cu−Zn−Au deposit, skarn type Fe, Cu, W polymetallic deposit, hydrothermal vein type Au deposit, sulfide type Cu−Ni−PGE deposit were formed. During the Mesozoic metallogenic period, gold, silver, copper, molybdenum, tungsten and tin mineralization of hydrothermal vein and porphyry/skarn types were mainly formed.
