摘　　要：甘肃北山地区属于中低山-干旱戈壁丘陵荒漠区,地形北高南低,岩石裸露,植被不发育。选择-4~+20目粒级的风化岩屑样品可以有效地排除风尘砂干扰。以瓜州县906金矿为例,介绍该地球化学景观条件下利用岩屑地球化学测量技术方法和应用效果。在此类景观区开展岩屑地球化学测量可以快速、准确地查明异常源,缩小找矿靶区,提高找矿效果,是行之有效的找矿方法。The 906 gold deposit in Guazhou County of Gansu province has theTopographic features of hilly area of middle low hill and Gobi desert,The terrain of 906 is high in the north and low in the south,the vegetation in this areais not developed and the rocks are exposed.So we Choosing-4~+20 meshes of coarse grain weathering cuttings can effectively eliminate the interference of wind-dust sand.Take the discovery of gold mine 906 as an example,this paper introduces the technique and application effect of the geochemical measurement method of cuttings under the condition of the landscape,the geochemical survey of cuttings in this arid desert geochemical landscape can quickly and accurately delineate the area of mineralized alteration zone and improve the prospecting effect.
