The Ashele volcanogenic massive sulfide (VMS) Cu-Zn deposit is placed in the Devonian volcanic-sedimentary basin of the Chinese Altay Orogen, NW China. It occurs in the form of well-developed lensoid orebodies within the Devonian Ashele Formation. The orebodies display analogous deformational characteristics with respect to their host rocks. Two periods of ore formation are distinguishable in the...
The Qiaxia Cu deposit occurs as veins controlled by NW‐extending structures in the Devonian volcano‐sedimentary Kelan Basin of the Altay orogenic belt, Xinjiang, China. Igneous and sedimentary strata exposed in the mining area have been subjected to greenschist‐facies metamorphism represented by an assemblage of chlorite–epidote–biotite ± garnet ± amphibole. The hydrothermal ore‐forming process can...
