query: What is the significance of the palaeohigh in relation to the Subathu Formation's distal nature and thin sequences in the western intermediate structural level localities?
answer: In the Lesser Himalayan early foreland basin, palaeohighs, resulting from basement fault reactivation, may have been located in the west between the load to the north and the marine Subathu basin to the south. This would result in shallowing towards, and reduced sedimentation on the palaeohigh, which coupled with the probable distal nature of the basin, explains the thin sequences of the western intermediate structural level localities.
