Abstract
Dongchuan is a famous copper producing area in China, where has good geological condition to form many copper deposits with local characteristics. This article summarizes the metallogenic regularities of Dongchuan copper deposits based on the previous works, research findings and the latest research advances. The study suggests that the Dongchuan copper-ore area has a good metallogenic background and immense prospecting potential. Copper ore is mainly found in Yinmin Formation, Luoxue Formation, Heishan Formation, Daqiaodi Formation, and in the Sinian-aged basement, and its occurrence is closely related to volcanic magmatism. The discussions regarding prospecting directions of Dongchuan copper ore were conducted based on the metallogenic regularity research, the results shows that further expanding of the exploration activities from the existing ore-bodies would be carried out; the breakthrough points focus on the Pingdingshan Formation, Qinglongshan Formation, and Daqiaodi Formation strata; at the same tine, more attention should be paid to the new types of deposits, such as Yanziya-type or hydrothermal deposits.
