[en] The history and advance of the deep-penetrating geochemistry, especially the MOMOE, electrogeochemistry and geogas measurement in the exploration for uranium resources are elucidated in this paper. With the progress of exploration for uranium resources in China, outcropped or shallow- buried deposits are fewer and fewer. Explore the deep-buried deposits become the challenging task for uranium geologists. Therefore, deep-penetrating geochemical methods are doomed to play an important role in the exploration for deep-buried and concealed uranium deposits in China. (authors)
