- •
Mesozoic MORB-type gabbros, high-Mg and normal diorites were discovered in the Ando area
- •
A new tectonic scenario was proposed to interpret the formation of these rocks
- •
The rocks were synchronously emplaced at 174–177 Ma
- •
Their generations were triggered by the asthenospheric upwelling
- •
The upwelling was resulted from a slab roll-back of the subducted Bangong–Nujiang Ocean
