- •
The out-of-sequence Zimithang Thrust crops out at high Himalayan structural levels.
- •
16–13 Ma Sill-gneisses in the hanging wall are thrust over 27–17 Ma Grt-schists in the footwall.
- •
Both footwall and hanging wall rocks yield 40Ar/39Ar muscovite ages of ~ 7 Ma.
- •
This dataset verifies the eastwards-younging Himalayan cooling trend.
