This paper looks back an over 20 years geological examination process of the Tongshuzhuang anomaly, Tongbai Mountains, Henan Province, from its recognition by regional geochemical mapping to ore discovery by drilling. In the process, the areas of geological survey has been gradually focused from Laoheshangmiao Au—Ag anomaly, through northern Laoheshangmiao Ag anomaly, to Tongshuzhuang—Laohudonggou Ag anomaly, and to Tongshuzhuang Ag anomaly; meanwhile, the survey scales enlarged from 1∶200 000, through 1∶25 000, to 1∶10 000, and to 1∶5000; the used methods include, from early to late, regional geochemical mapping, local geochemical mapping, geological—geochemical profile meterage, geophysical measurement and localization, and trenching and drilling. Interpretation of the anomaly has been changed from orecausative, through nonorecausative, and back to orecausative, with its source changed from carbonaceous schist intercalations within marbles to concealed granite porphyry. This retrospect shows the difficulty of deep ore exploration, the necessity of recycled practice—understanding, and the importance of intergrated application of advanced metllogenic theories and exploration techniques.
