Zircon U-Pb age and geochemical characteristics of ore-bearing granodiorite porphyry in the Duobuza porphyry copper deposit, Tibet

The Duobuza deposit is the first porphyry-type copper deposit discovered with giant prospect in the Bangongco metallogenic belt. Geochemical data indicates that the ore-bearing Duobuza granodiorite porphyry is high-K calc-alkaline to shoshonitic and peraluminous composition. The ore-bearing granodiorite porphyry is enriched in large-ion lithophile elements(LILE) such as Rb, K, Th, La, Ce and Sr, and depleted in high-field-strength elements(HFSE)...
