Tropical rain forest areas feature strong chemical weathering, thick weathered layers, developed vegetation, and less exposed bedrock. It is one of the essential geological survey contents of tropical rainforest areas to obtain geological and mineral information of coverage areas by effectively utilizing overburden layers. This paper summarizes the geological and mineral information detection methods employed in exploring the geological and mineral exploration technologies in the tropical rainforest area in the Nanhanzhai experimental area, Mengman town. In detail, the methods were dominated by soil geochemical survey and sampling drill and combined geological route survey. The geological boundaries obtained using these methods roughly coincide with 1∶50,000 geological maps, and three integrated anomalies with certain prospecting prospects were delineated using these methods. This study can serve as a reference for preparing the technical guide to geological mapping methods suitable for tropical rainforest areas.
