摘要:

沟系岩屑测量法是一种非正规的土壤地球化学找矿方法,其采样介质为残坡积物和岩石碎屑。在矿产资源调查评价中,该测量法可以快速地对1∶20万、1∶5万水系沉积物异常及土壤异常等进行检查,具有快速、经济且准确圈定矿化范围的特点。2010年,为了迅速缩小1∶20万水系沉积物测量异常范围,有效浓缩异常浓集中心,利用沟系岩屑测量法在阿木尼克地区快速圈定了一处具有一定规模的钼铅锌综合异常,通过检查发现1条钼矿体。研究表明,沟系岩屑测量法及其采用的技术指标在柴达木盆地周缘荒漠化中高山干旱剥蚀景观地区的地质找矿中起到了很好的作用,找矿效果显著,具有一定的推广意义。

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
