摘　　要：利用水系沉积物测量方法,对津巴布韦奇马尼马尼地区的元素分布特征、相关性和矿点的成矿地球化学模式进行研究,建立了金与共生元素的回归模型,并且根据区内的异常特征、空间分布规律等优选出6处成矿远景区,其中塔卡是本区寻找热液蚀变型金矿的有利区段,其余5个地区是寻找铜、镍、钛等矿床的成矿远景区。The authors analyzed the element distribution characteristics, element correlation and geochemical mineralization model of ore spots in Chimanimani area of Zimbabwe by means of stream sediment survey, established the regression model for gold and associat- ed elements, and delineated 6 metallogenic prospective areas according to the abnormal features and regularity of spatial distribution and through optimization, with Tarka prospective area as the potential area of hydrothermal alteration type gold deposit, and the other 5 areas as the main exploration targets for copper, nickel, titanium deposits.
