The Jurassic sediments exposed in these Vwo zones differ structurally as well as
lithologically . In the allochthonoris zone the imbricate structure has resulted in
repetition and thickening of beds as well as cropping out of Triassic and earlier ...

Whereas the autochthonous zone was initially upwarped during the Late Jurassic
, it was deformed during the main Himalayan Orogeny ( Oligo - Miocene ) . The
allochthonous zone , probably , was first affected by gravity faulting ( rifting ? ) ...
