摘要:

内蒙古中东部半干旱荒漠草原景观区选择B层-5~+40目粗粒级的风化岩屑样品可以有效地排除风成砂的干扰,突出成矿及指示元素的地球化学异常特征。以内蒙古西乌珠穆沁旗白音查干银(金)多金属矿床的发现为例,介绍该景观条件下开展岩屑地球化学测量的方法技术以及应用效果。在半干旱荒漠草原景观区开展岩屑地球化学测量可以快速、准确地圈定出矿化蚀变带的范围,提高找矿效果,是行之有效的找矿方法。

Abstract:

In the semi-arid desert and grassland landscape area in Inner Mongolia,geochemical debris survey sampling tests show that the thick grain size(-5~+40 mesh) of weathering debris samples from B layer of soil can effectively remove the interference of eolian sand,and it also can stand out the geochemical anomalous characteristics of mineralization and indicating elements.Take the dicover of Baiyinchagan Ag(Au) polymetallic ore deposit for example,we analyze the methods,technologies of geochemical debris survey and its exploration application.it is demonstrated that geochemical debris exploration method is a good prospecting method,as it can quickly,accurately enclose the range of the mineralization alteration zone,and improving the prospecting effect.
