Abstract Using the geochemical pattern lineage and the theory of usable elements for mineralization, the authors, based on 1:50000 regional geochemical data of Zhongtiaoshan area, have made divisional processing of the original data from the ore-forming belt in accord with Jiangxian Group and Zhongtiao Group, and re-delineate the anomalies. The part of metal quantity higher than the threshold was regarded as the usable metal quantity for mineralization, and the ratio of the proved resource reserves to the prognostic resource quantity in the anomaly was regarded as the metal quantity suitable for mineralization. Calculation shows that the metal quantity suitable for mineralization is 32%. The total resource quantity and the potential resource quantity were also predicted. On the basis of anomaly characteristics, metallogenic geological conditions and resource quantity prognosis, the authors hold that the outskirts of the Tongkuangyu ore district and the areas around Beiyu brachyanticline are major places for further ore-prospecting work.
