The heat released halogen method, a deep-penetrating geochemical method for ore exploration, has not been used extensively yet. The authors carried out the research on the feasibility this method in the Hucun copper deposit of Anhui Province characterized by moist hills and low mountain eluvial-slope wash covered geochemical landscape area. Based on a comparison of soil heat released halogen with the conventional soil survey, the authors have reached some conclusions: The heat released halogen method has more advantages than the conventional soil survey in that it can effectively eliminate the interference of rock body. The indicating significance of conventional soil halogen anomalies is limited and has no universality. The element anomalies of conventional soil survey are impacted by rock body or its contact zone and superficial mineralization, and hence their indicating significance has limitation; nevertheless, the barium negative anomaly area has a fairly good indicating significance for hydrothermal alteration zone. The heat released halogen anomalies correspond well with deep orebody space, the element content has similar change tendencies, and the heat released halogen anomalies appear on the surface of the vertical projection part of the orebody, which is consistent with previous conclusions. It is tentatively held that we can try to use the heat released halogen method at the deep orebody positioning stage in the Yangtze River hill and low mountain eluvial-slope wash covered geochemical landscape area.
