Revealing the mechanism of metal enrichment in upper crust is important for understanding the formation of giant porphyry Cusbnd Au system. Whereas, it remains unclear when and how this enrichment process operated in a collisional setting. In this study, abundant Neoproterozoic biotitite xenoliths, entrained by Eocene monzogranite porphyries, are …
The Beiya gold polymetallic ore deposit is one of the largest gold deposit in the world. Previous studies have suggested the formation of the Beiya deposit is closely related to the porphyritic alkaline intrusions. Different tectonic models have been proposed by geologists to explain the alkaline intrusions. However, no consensus has been reached and data for …
