| 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;中部的高镍异常区是寻找红土型镍矿的有利部位。 |
| 英文摘要: |
| According to the results of regional geochemical survey at scale 1:250000 and geological, geochemical and remote sensing data in the east Zimbabwe are carried out studies on geochemical characteristics, metallogenic pattern and ore prediction and it is established that Tarka area should be concentrated on gold prospecting, Limeworks,Mutema area on Ni,Cu prospecting. Gold deposits in Tarka area are not formed by secondary enrichment of dolerite. They are controlled by structure and related to gold mobilization and enrichment during the hydrothermal activities. The strong Ni anomly in the middle part is favorite for lateriric Ni deposits. Results of the study show further prospecting direction in the area. |
