中文摘要:
      尼亚加索拉金矿区位于西非克拉通几内亚东北部锡吉里盆地,虽经历近十年的勘查开发,但一直缺乏其成矿方面的研究。笔者通过分析成矿地质背景、矿区地质特征和总结目前地质勘查工作成果,初步厘定了矿区构造变形期次与成矿的关系,揭示了矿区中发育的3期构造变形作用都对成矿起着促进作用,矿体产出受岩体内外接触带、层间裂隙及断裂旁侧裂隙带的控制。已有的地质资料均显示该矿区成矿条件优越,具有大型—超大型金矿的找矿潜力。
英文摘要:
      The Niagasola Gold District located in Siguiri Basin, Northeast Guinea, West African. Although it has undergone exploration and development for nearly ten years, there has been a lack of research reports on mineralization. Based on the geological setting of deposit and feature of ore district, together with the results of the current geological exploration, aims to determine the relationship between the structural deformation and the mineralization. Results show that the deposit was developed by three-stage tectonic deformation and was controlled by the contact zones and fractures of interlayer and beside the fault. Generally, the Niagasola Gold District is featured by superior mineralization conditions and the prospecting potential of giant gold deposits.
