Abstract:Using the foam trap and liquid trap, the authors carried out large-scale geogas survey in the Jinwozi V210 concealed gold deposit located in the boundary between Hami of Xinjiang and Anxi of Gansu, and studied the field application of the geogas survey method. The results indicate that Au geochemical anomalies are quite clear over the ore deposit and are associated with some other anomalies such as Cu, Pb and Fe. The anomalies found at the surface are related to the depth and attitude of the ore body and the structures. The REE patterns of the trace elements collected in the process of this survey are similar to patterns of the trace elements collected from the ore body, suggesting that the trace elements over the gold deposit were derived from the buried ore body. This study shows that the deep-penetrating geochemical method for concealed ore deposit prospecting in gobi area has promising future.
