- •
The Eocene adakite-like rocks occur widely in Western Yunnan, southeastern Tibet.
- •
The adakites in the east of W Yunnan were derived from the partial melting of Neoproterozoic mafic rocks.
- •
The adakites in the west of W Yunnan resulted from the partial melting of Paleozoic–Mesozoic mafic rocks.
- •
Spatial changes of Hf and Nd isotopes of the adakites related to distinct components of the lower crust of W Yunnan.
- •
The adakites related to removal of thickened lithosphere during the collision orogeny.
