The integrated geogas survey is a prospecting technology that integrates geogas survey and X-ray fluorescence measurement for exploring concealed ores based on the prospecting needs of pegmatite-type rare metal deposits. This technology utilizes handheld X-ray fluorescence instruments for rapid measurement to capture secondary or primary halos on the surface, enabling the evaluation of the occurrence positions, strikes, and extension lengths of ore-hosting pegmatite veins on the surface. Moreover, it employs a dynamic geogas survey to capture deep mineralization information for evaluating the deep ore-bearing potential and extension depths of the pegmatite veins. This study demonstrated the main technical methods of the integrated prospecting technology and the application cases of ore prospecting supported by relevant projects in different geochemical landscape environments, in order to provide reference for the extension and application of this method and subsequent prospecting word in similar landscape areas.
