a The central Bengal basin is shaped by the Ganges River, the Indo-Burman megathrust deformation front and foldbelt growth, and the Shillong Massif thrust and uplift, among its fluvial and tectonic agents. b Coring and luminescence sampling was executed across a vast, underfilled paleochannel evident on the Ganges floodplain surface and at an adjacent dry pond with seismite features. c The perimeter of the drained pond at the time of fieldwork. The pond walls and floor revealed extensive sand dikes, fluidized muds, and liquefied sand layers, which were sampled for luminescence dating. The background images for panels a and b show relative surface topography from NASA SRTM elevation data.
