摘要
根据勘查地球化学与勘查地球物理找矿方法中的理论,分析了青海省大柴旦地区的找矿地质背景,在此基础上对该地区的成矿条件进行研究。通过在该地区开展1∶5万水系沉积物测量和1∶5万高精度磁法测量,分析该地区的找矿远景区,优选了3个多金属综合异常区,为下一步的找矿工作提供重要的靶区依据。
Target area determination is one of the most important works for ore prospecting. Based on prospec- ting theory of geochemical and geophysical exploration, the data obtained from 1.. 50000 stream sediment and 1 ~ 50000 magnetic survey in the Dachaidan area, Qinghai Province is analyzed in combination with the geological background of the area, and three areas with polymetallic anomalies are identified. The result provides important information for future ore prospecting in the study area, especially the determination of the target area.
