Distribution and Migration of Gold in Gobi-Overlay of Arid Desert Terrain: Take the Jinwozi 210 Gold Belt in Xinjiang as an Example
详细信息   
摘要


     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.
