摘　　要：尼昂华莱地区位于坦桑尼亚西北部,维多利亚南部苏库玛兰德绿岩带内,该地区多发育条带状铁建造型金矿床,矿体赋存于条带状铁建造内的剪切带中,表现为明显的层控型特征。通过对已发现矿床地质特征进行分析,结合磁异常特征、电法异常特征及土壤地球化学特征,对尼昂华莱地区条带状铁建造型金矿床勘查方向进行了分析,认为在目前民采活动的基础上,该区域的勘查方向首先为寻找隐伏绿岩区域,其次为整合开发,以期取得较大的突破。Nyang'wale area is located in the northwestern part of Tanzania,within the Sukumaland greenstone belt to the south of Victoria.The area hosts multiple banded iron formation-type gold deposits,with ore bodies occurring in shear zones within the banded iron formation,exhibiting distinct stratigraphic control characteristics.Through the analysis of the geological characteristics of the discovered deposits,combined with magnetic anomaly features,electrical anomaly features,and soil geochemical characteristics,the prospecting direction of the banded iron formation-type gold deposits in Nyang'wale area was analyzed.It is suggested that,based on the current mining activities,the primary prospecting direction in this area should focus on the search for concealed greenstone areas,followed by integrated development,in order to achieve significant breakthroughs.
