以新疆金窝子金矿田210金矿带为例，实验研究了该区地气和土壤活动态测量等深穿透地球化学方法的效果。实验表明地气测量和土壤活动态测量可以有效地反映覆盖层下隐伏矿体。揭露矿体覆盖层的钻孔研究表明，金活动态形式具有“C”型分布特征。采集矿体上方地表异常位置土壤孔隙中地气、土壤样品，使用透射电子显微镜（TEM）实测样品中微粒物质的粒径、形貌和成分，在地气和土壤中观测到了 Au -Cu、Au -Bi 成矿元素纳米微粒，此微粒是形成地表深穿透地球化学异常的物质，来源于覆盖层下隐伏矿体。微粒到达地表，可以形成地气和土壤活动态异常。纳米微粒具有可从土壤颗粒表面分离的性质，在其向上迁移过程中，可以从吸附固定状态解吸，此性质可以用于解释活动态异常在钻孔垂直剖面上的“C”型分布。

The deep-penetrating geochemistry methods for geogas and mobile elements survey were evaluated in Jinwozi 210 gold belt,Xinjiang.The experimental results in this paper confirm that these methods can effective-ly indicate the concealed ore bodies under the regolith cover.The drilling investigations revealed the “C-shape”distribution patterns of the mobile gold.The geogas and soil samples in surface anomalies were collected,in which the size,morphology and component of the particles were characterized by transmission electron micro-scope.Gold-copper and gold-bismuth nanoscale particles were observed in the geogas and soil samples.It is be-lieved that the nanoscale particles sourced from the underlying concealed ore bodies are likely to cause the sur-face geochemical anomalies.The nanoscale particles could travel upwards to the surface,during which the geogas and soil anomalies were developed in pore space and soil.The dissociation and desorption of the nanoscale particles from soil particles’surface during their migration upwards probably created the “C-shape”distribution patterns of the mobile gold in vertical profiles in drilling holes.
