...Yani Najman; Andy Carter; Grahame Oliver; Eduardo Garzanti Abstract In contrast to Eocene Himalayan foreland basin sedimentary deposits in India and Pakistan, coeval sedimentary rocks of the Bhainskati Formation in Nepal contain scant petrographic evidence of orogenic input. Such data have been...
