虎拉林金矿床是额尔古纳成矿带北段的一个中型规模的金矿床,矿体产于爆破角砾岩中。该矿位于华北板块和西伯利亚板块之间,是斑岩和爆破角砾岩型金矿床发育地区之一。金矿床成矿年龄为135 M a,矿化角砾岩具有典型隐爆角砾岩的特征,矿化在时空和成因上与爆破角砾岩关系密切;3δ4S变化范围为-0.2‰~0.8‰,具有深源岩浆硫特征;S和Pb同位素、流体包裹体、稀土元素等特征表明成矿物质来自地壳深部或地幔,成矿流体具有以深部岩浆热液为主的特点。由此可知,虎拉林金矿床是典型的隐爆角砾岩型金矿。
The Hululin gold deposit is a medium-sized gold deposit to the north of the Erguna metallogenic belt and is hosted in blasting breccias. Located between the North China plate and the Siberian plate, the mine is one of the most developed porphyry and breccia breccia-type gold deposits. The mineralization age of the gold deposit is 135Ma. The mineralized breccia has the characteristics of typical crypto-explosive breccia. The mineralization is closely related to the breccia and breccia in space-time and genesis. The range of 3δ4S is -0.2 ‰ ~ 0.8 ‰ , With deep-sourced magmatic sulfur characteristics. The characteristics of S and Pb isotopes, fluid inclusions and rare earth elements indicate that the ore-forming materials come from deep crust or mantle, and the ore-forming fluids are characterized by deep magmatic hydrothermal fluids. It can be seen that Hululin gold deposit is a typical cryptoexplosive breccia type gold deposit.
