Abstract:

Ravine System Rock Debris Survey method is an unformal soil geochemical exploration method,its sampling medium is sediment and rock fragments.In mineral resources investigation and appraisal，you can quickly check the exception of 1∶200 000,1∶50 000 stream sediment,soil anomalies,it has a rapid,economic,accurate delineation of mineralization range.In order to narrow 1∶200 000 sediment survey abnormal,and concentrate anomaly concentration center effectively,using ravine system rock debris survey delined a largest molybdenum lead zinc comprehensive anomaly rapidly,one molybdenum ore body was found after checking.It shows that Ravine System Rock Debris Survey method and its technical indicators are very useful in Alpine arid Erosion desertification landscape area of Qaidam Basin margin,it plays a very good role in prospecting exploration,and has a potential significance.

Key words: Ravine system rock debris survey method, Molybdenite deposit, Application effective, Amnick area, Qaidam Basin
