| Abstract: | The Galale gold(copper) deposit is located in the west section of Bangong lake-Nujiang suture zone in Tibet.It is a gold(of large scale) and copper(of small scale) skarn deposit.There are mainly huge porphyritic quartz diorite,middle-fine grain granodiorite and diorite porphyrite in the mine area.The REE differential degree of rock sample in this ore deposit has a relatively higher value,and Eu negative anomaly is weak.The content of Al2O3 is 14.45%-15.84%.The aluminum supersaturation index(A/CNK) ranges be... |
