| 摘 要： | 坦桑尼亚马拉省尼亚斯罗利金矿区位于坦桑尼亚马拉—穆索马绿岩带,矿床类型为受剪切构造带控制的构造蚀变岩型金矿床,剪切构造带严格控制着金矿化作用的范围。在总结矿区成矿地质特征和物探、化探综合异常特征基础上,通过对该矿区进行成矿地质条件分析、物化探测量及钻探查证工作,了解第四系覆盖区下方含矿构造蚀变带分布及金矿(化)体的富集地段,建立了尼亚斯罗利金矿区的物化探综合找矿评价标志,为矿区的下一步找矿工作指明了方向。

| Abstract: | Located in the greenstone belt of Mara-Musoma,Tanzania,the Nyasirori Gold District is the tectonic altered rock type gold deposit controlled by the shear zone that strictly controls the gold mineralization.The paper summarizes the regional geological characteristics and the comprehensive anomalous characteristics of the geophysical and geochemical prospecting,and carries out the metallogenic geological condition analysis,geophysical and geochemical measurement and drilling verification in the region,based on which the distribution of ore-bearing structural alteration zone beneath the Quaternary overburden and the concentration segments of ore (mineralized) bodies are revealed,the geophysical and geochemical prospecting criteria or indicators of the Nyasirori gold district are established.The research points out the prospecting direction of future exploration work. |
