| Abstract: | A field geological survey,a petrographic study and a whole-rock geochemical analysis are performed on the rock of the Gaerqiong medium-sized Cu-Au deposit in the western segment of the Bangonghu-Nujiang suture zone.The results are as follows.Quartz diorite and granite porphyry are rich in large-ion lithophile elements(LILE),such as Rb,Ba,Th and U,but devoid of high-field-strength elements(HFSE) like Nb,Ta,Zr and Hf.Furthermore,Rb/Sr is far above one.Negative Nb and weak negative Eu are abnormal and the frac... |
