| Abstract: | The Mangzong porphyry Cu-Mo deposit is located at the middle of the Yulong porphyry copper ore belt in the eastern Tibet with outcrop area of 0.27km2. The Mangzong porphyry which associated with Cu mineralization intruded the Lower Permain siltstone interlaid with limestone and underwent strong alteration. The porphyry consists mainly of early stage diorite granite porphyry and late stage quartz monzogranite porphyry and K-feldspar porphyry. The early stage porphyry and late stage porphyry are different in ... |
