中文摘要:
      根据津巴布韦东部地区1:25万区域地球化学调查成果,运用地质、化探、遥感等对该地区进行了地球化学特征、成矿规律研究和找矿预测。确立了以金为主的Tarka地区和以Ni、Cu为主的Limeworks、MUTEMA地区为找矿靶区;认为TARKA地区金矿并非粗玄岩次生富集而成,而是受构造控制并与热液活动引起的金活化富集有关;同时中部的高镍异常区是寻找红土型镍矿的有利部位。为今后该地区地质找矿工作提供了方向。
英文摘要:
      According to the results of 1:250000 regional geochemical survey in the eastern region of Zimbabwe, By utilizing the method of geological, geochemical and remote sensing, and so on, The geochemical characteristics, metallogenic regularities and prospecting prediction were researched in the region. Determined the prospecting target area, Tarka region is as the main minerals of gold , Limeworks and Mutema region are Ni-Cu as main minerals; Thinking the Tarka gold deposit is not formed by the dolerite secondary enrichment, but controlled by tectonic and associated with the gold activation and enrichment Caused by hydrothermal activity. At the same time, high nickel anomaly region is the advantageous position for Looking for type laterite nickel ore. It provides a direction for the future of the geological prospecting work.
