Singtali and Subathu formations
Following a sedimentary break or unconformity, the Singtali and Subathu formations were deposited as foreland basin sediments in the Garhwal Outer Lesser Himalaya during the Late Cretaceous to Middle Palaeocene. Both formations can be found overlying the Tal Formation in an extremely complex structural setting including isoclinal overturned folding and multiple thrusting events. In addition, with the similarities of the lithology as well as depositional environment, it is sometimes quite difficult to distinguish between the Singtali and Subathu Formations. The main difference discussed in the following is related to the tectonic events during their deposition.
