Post-collisional potassic magmatism in the eastern Lhasa terrane, South Tibet: Products of partial melting of mélanges in a continental subduction channel
Zircon U–Pb ages of the YPVR are 10.61 ± 0.10 Ma and 10.70 ± 0.18 Ma, respectively. The YPVR were generated by AFC process of mantle-derived ultrapotassic magmas. Ultrapotassic magmas resulted from partial melting of the Indian mélange rocks.
