中文摘要:
      黔东南地区,大型扇形复式背斜—“黔东南复背斜”是区内金矿床Ⅰ级控矿构造,次级褶皱和断裂为Ⅱ级控矿构造,在复式背斜轴部张性环境易于形成石英脉型矿体,翼部压剪性环境易于形成蚀变岩型矿体。区内金矿床成矿物质及流体主要来自于地层围岩,但其中锦屏地区的平秋、八克、同古等金矿床成矿物质及流体具有深源的特征,反映了锦屏地区平秋—八克—同古一带有岩浆活动参与到成矿系统中,深部可能存在与岩浆热液有关的大型金矿床,极具找矿前景。
英文摘要:
      In southeastern Guizhou Province, the anticlinorium is the first-order, and its secondary anticlines and faults are t second-order ore-controlling structures of the gold deposits, respectively. Quartz vein type orebodies are likely to occur in the core of the anticlinorium, while altered rock type orebodies tend to form in the compressive –shear wing of the anticlinorium. The wall rocks are the main sources for the metallogenic materials and fluids, while those in Bake, Pingqiu and Tonggu gold deposits in the Jinping area show characteristics of deep source, suggesting contributions of magmatic activity. Thus, the Jinping area has a considerable prospecting potential to find large gold deposits related to magmatic fluids at depth.
