摘要
Most terrestrial volcanic-intrusion related-Cretaceous iron deposits along the middle-lower Yangtze River Valley developed in Cretaceous basins whereas a few,such as the Chengchao and Jinshandian skarn iron deposits,occur in uplift area.In this paper based on the porphyry iron mineral model the authors suggest a polymetallic iron deposit model comprising the major characteristics of the four ore systems. The varied ore systems and ore types are indicators each other for prospecting.
