    摘要
  • 三道湾子金矿位于大兴安岭燕山期成矿带东南部，为典型的石英脉型岩金矿床.通过对含矿石英脉、石英脉围岩及同期火山岩地球化学特征的研究，探讨了石英脉围岩及同期火山岩的成矿地质构造背景.证据表明三道湾子岩金矿成矿母岩的地球化学成分类似埃达克岩，或有学者所称的“C型埃达克岩”.成矿流体同成矿母岩可能同时形成于来自上地幔的的玄武岩，为上地幔玄武岩底劈上侵到加厚的地壳（>50 km）底部导致下地壳基性岩部分融熔形成的，其成因并非可以用浅成低温热液作单一解释.
    Sandaowanzi gold deposit in Heilongjiang Province, located in the southeast of Yanshanian Daxinganling metallogenic belt, is a typical quartz vein deposit. Based on the study of geochemical characteristics of the ore-bearing quartz vein, surrounding rocks and corresponding volcanic rocks, the authors discuss the geological background for the mineralization. Evidences show that the ore-forming rock of the Sandaowanzi gold deposit is geochemically similar to adakite, or referred to as "C-type adakite". It is suggested that the mineralized fluid and the parent rock be both derived from the basaltic magma of the upper mantle, when the basalt intruded upward into the thickened formation of the lower crust (>50 km) following the deep faults, causing partly melting of the mafic rocks and forming of the gold deposit. Epithermal mineralization seems not the only interpretation for the genesis of the Sandaowanzi gold deposit.
