| Techniques for Anomaly Investigation in High and Cold Desert Region: A Case Study of the Discovery of the Longweigou Copper and Gold Deposit in Qinghai Province |
| The anomaly investigation in the high and cold desert region is very difficult and of low efficiency because of the unique geographic features. The anomaly investigation in regions of such landscape should be carried out with non-conventional methods and based on detailed studies of such factors as anomaly characteristics, ore-control geological conditions, working scale and object scale. Composite and integrated techniques were adopted in Longweigou area, Qinghai Province. On the basis of interpretation of 1∶50,000 remote sensing images, the X-ray fluorescence method was used and in-situ rapid analysis was conducted in association with basic geological route investigation. As a result, the goal of rapid anomaly inspection was achieved. It can be concluded that the composite and integrated techniques put forward in this paper are effective in anomaly investigation of high and cold desert regions. A breakthrough was made in the ore prospecting work of Longweigou area, and Cu-Au ore (mineralized) bodies with economic potential were disco-(vered) for the first time on the southern margin of the Altun Mountains. |
