摘　　要：在干旱高山景区,以沟系岩屑测量对1∶5万水系沉积物异常进行检查,可达到快捷、经济、准确圈定矿化范围的目的。沟系岩屑测量是一种非正规网度的地球化学找矿方法,采集对象为风化过程中滞留在基岩表面和残破积层表面的岩屑。1998年青海省地方地勘项目《青海省茫崖行委采石沟—红水沟地区普查》工作中,利用沟系岩屑测量圈定了6处综合异常,并通过Ⅱ级查证,发现了4条含金矿化带。说明沟系岩屑测量在采石沟地区矿产资源评价工作中发挥了很好的指导作用。In the high mountain area under arid climate, the anomaly of stream sediment survey was cheeked by ravine system debris survey. It is quick, economical and precise for outlining the spatial distribution of mineralization. Ravine system debris survey is an informal networking geochemical exploration method. The collecting target is debris which is detained on the surface of bedrock and eluvium after the wind transportation of plasma. In the prospecting project ＂The mass screening of Caishigou-Hongshuigou area in Mangya, Qinghai＂ in points within composite anomaly were trapped by the four belts of mineralization zone with gold were found. Qinghai province, 1998, six ravine system debris survey, and through grade-Ⅱ checking, It shows that ravine system debris survey plays an directing role in the mineral resource evaluation work of Caishigou area.
