Abstract:

In order to further verify whether the hydrocarbon-mercury superimposed halo method has universality in deep prospecting prediction,a hydrocarbon-mercury superimposed halo deep prospecting test was carried out in the Wangu gold mining area and its periphery in the northeast section of the Xuefeng arc.By analyzing the evolution of hydrocarbon-mercury components of different geological bodies and different elevations in the known mining areas,and the comprehensive abnormal structure,superimposition chara-cteristics and spatial correspondence of hydrocarbon-mercury in the upper soil of the ore body,the deep prospecting in the peripheral Jiangdong ore section is guided.The results show that the soil geochemical field in the Wangu mining area and its surrounding Jiangdong mining section also has a syngenetic superimposition field and a deep source superimposition field.The syngenetic superimposition anomaly is due to the stratum, and the correlation between Au and hydrocarbon components is poor. Hydrocarbon mercury anomalies are in a dispersed state, with relatively low anomalous intensity.Deep source superposition anomaly is the superposition of ore-forming materials caused by deep source fluids(magma or mantle source),and Au has a good correlation with hydrocarbon mercury.The hydrocarbon mercury anomaly center is prominent and the anomaly intensity is strong.The hydrocarbon anomaly patterns are mainly multimodal and dual bimodal anomaly patterns.Hydrocarbon anomalies appear in multimodal patterns,indicating that there are multiple parallel blind veins in the deep,and the dual in the bimodal abnormal pattern,only the head abnormal peak appears,but the tail abnormal peak has not yet appeared.It shows that the ore body extends well to the deep indicating that the mineralization has not yet ended,and there is still a good prospecting potential in the deep part.Through engineering verification,good prediction results have been obtained in the red bed coverage area of Jiangdong ore section.It is proved that the method has good universality.

Key words: syngenetic superposition anomaly, deep source superposition anomaly, deep metallogenic prediction, hydrocarbon-mercury superimposed halo method, Wangu gold deposit, Hunan Province
