Abstract
Since discovery of Chengmenshan ore deposit in fifties last century it has been prove a large "three combination to one" Cu polymetallic deposit.Metallogenetically,it is related to gransdioritic porphyry and quartz porphyry.Based on the previous data and working result on the spot show that the gransdioritic porphyry and quartz porphyry are related in their evolution and their emplacement mechanism differ from each other and differ in their rock-forming time and netallogenic attributes.The primitive magma before evolution and differentiation may have been uplifted by basement dome in Jiurui area and in the late stage the gransdioritic porphyry was differentiated and was uplifted again and its passive emplacement and meso-epithermal and meso-high temperature ore elements motivation and enrichment occurred as Cu,Zn and Au deposits then followed the tectonic overprinting which resulted in connection of the faults to the residual magma and the the active emplacement and related Mo deposit associated with the quartz porphyry.关键词
