1:25万汪清县和春化幅地球化学数据更新效果评价

The evaluation of the effect about the geochemical exploration of 1:250000 in Wangqing County and Chunhua sheets by new method over again

通过新方法技术开展1:25万区域化探数据更新的成果与1:20万化探资料的对比,充分反映出1:25万区域化探更新数据更能客观的反映区域地质构造和成矿地质背景的地球化学特征,所获取的地球化学找矿信息更为清晰准确。为此在覆盖层较厚的森林沼泽景观区重新开展1:25万化探扫面是十分必要且迫在眉睫。

The 1：250 000 regional geochemical data over again can objectively relfect the geochemical features of regional geological structure and geological background of mineralization, by comparing the new method of 1：250 000 regional geochemical data over again with 1：200 000 regional geochemical data ago. The geochemical prospecting information is more clear and accurate. It is very necessary and imminent to carry out 1：250 000 the geological exploration in area where is the thick cover of forest and swamp landscape over again.
