- •
We found a late Eocene–early Miocene gneiss dome system in the Tengchong Terrane.
- •
Four gneiss domes are bounded by coeval detachments and strike-slip shear zones.
- •
Detachments caused mid-crustal decoupling and fast SW-ward extrusion of deep rocks.
- •
Parallel dextral strike-slip shear zones controlled extrusion and clockwise rotation.
- •
We propose a lithospheric bending model around the Indian indenter since late Eocene.
