Abstract
The Jiaoshidong Fe-Cu deposit is situated in the middle section of alkaline porphyry Cu multimetallic metallogenetic zone in the west margin of Yangzi platform, which occurred in the skarn zone of the lower wall of Yanshanian granite porphyry.In this paper,we have the analysis and study of the geological setting of metallogenesis,geological characteristics of deposit and orefield and have a discussion about the deposit genesis.We think that this ore deposit belongs to the type of land facies subvolcanic——hydrothermal high T to middle T skarn multimetallic deposit,which can provide a theoretical basis for the geological exploration of it in the future.
