| Abstract: | The composite stock of Indosinian epizonal syntexis adamellite diorite porphyrite, quartz diorite porphyrite and adamellite porphyry is the ore - bearing original rock body of Xuejiping porphyry Cu deposit. The planar alteration zone is developed. The ore deposit experienced the superimposed metallogenesis of pneumatolito - hypothermal, middle - low temperature hydrothermal and low temperature hydrothermal activities. The disseminated and stockwork Cu metallogenesis is developed in the K alteration zone and quartz -sericitization zone. We believe that the most hopeful formation areas of large scale porphyry Cu deposit are Pulang and its south part, Disuga in this region. |
