摘要
The Langyashan copper deposit in Chuxian, Anhui Province, is part of the Lower Reaches of the Yangtze River metallogenic belt, where the largest copper deposit associated with gold was found so far in east Anhui Province. There are few case studies on geochemical features of the Chuxian magmatie intrusion that closely related to the mineralization. Based on field geological survey, a suit of samples from the Chuxian magmatic intrusion and Shangyapu magmatic intrusion was analyzed. The results show that these Yanshanian intrusive rocks have geochemical characteristics similar to those of adakite. Moreover, the authors found a pulse of silicified shattered dolomite belt with micron pyrite on the north-west side of the Chouxian magmatic body occurring as siliceous vein and polymetallic mineralization around the Shangyaopu magmatic body.
