Abstract

This study aims to explore the feasibility of the carbon dioxide (CO₂) and sulfur dioxide (SO₂) gas geochemical survey method for mineral exploration in forested areas. Based on the newly designed gas rapid analysis instrument, this study conducted an experimental investigation of the method in the forested Jiapigou gold concentration area, Jilin Province. The results show that significant CO₂ and SO₂ anomalies were observed above the concealed ore bodies and structures. In the forested area, the CO₂ and SO₂ gas geochemical survey method reflected the fault structures and effectively indicated the deep concealed gold deposit. This method holds critical significance for the breakthrough of prospecting technology in China's covered areas.

Key words： carbon dioxide sulfur dioxide gas geochemical survey forested area Jiapigou gold concentration area
