Abstract
The Cuonama complex body in Yajiang county of Sichuan Province is located in the east part of the middle Ganzi-Litang fracture zone.It consists of the Rilema,Gexi,Cuonama,Goulong,Xiadechai and Duolong rock bodies,and the lithology is mainly quartz diorite,biotite granodiorite,biotite monzonitic granite and granite porphyry.This complex body belongs to a comagmatic evolution succession which was formed in the Late Triassic.This work analyzed the characteristics of petrology,petrochemistry,petrogeochemistry,alteration and mineralization of this complex body,and did comparative study with typical tungsten-tin mineralized granite (the Naling ore-bearing granite in South China,Yanshanian tungsten-bearing granite porphyry in Dahutang area in Jiangxi Province and New England tin-bearing granite) and the Yulong Porphyry and the ore-bearing granite porphyry in western margin of the Yangtze Platform.We confirm the ore-bearing potential of these rock bodies,and infer that the late-stage rock body has undergone the strongest mineralization with the increasing magmatic evolution.It is thus suggested that the late-stage Gexi granite porphyry body is a metallogenic geological body and should be a mineralization center in the study area.This work provides important prospecting direction of the study area.关键词
