(a) Structural fabric of the Hatia Trough and the Bay of Bengal with its present kinematic setting (after Maurin and Rangin, 2009). For the kinematics, the black arrows show the motion of the India Plate with respect to the Burma Plate and the Sunda Plate (I/B and I/S, respectively). (b) East–west schematic cross section across the Indo-Burmese subduction system showing the kinematics and geometry of the major structures in depth (modified after Alam et al., 2003; Maurin and Rangin, 2009; Hossain et al., 2019). The location of the section is shown in (a). (c) Schematic 2D model showing the tectonic evolution of the structures in the eastern Hatia Trough and the western Chittagong Tripura Fold Belt. The 2D restoration of the cross section across the eastern part of the Hatia Trough indicates approximately 0.6% and approximately 1.2% shortening for the base of the Dupitila Formation and Tipam Group, respectively. However, to the east, 2D restoration of the cross section across the western Chittagong Tripura Fold Belt indicates approximately 7.0% and approximately 13.5% shortening for the base of the Dupitila Formation and the Tipam Group, respectively.

Schematic stratigraphic cross section of the Surma Group and Tipam Formation of the Indo-Burman Ranges. A) Geologic map of observed facies at key locations (white stars) along the main road to Lengpui Airport (inset map, Fig. 2 shows location in Mizoram). Most contacts are inferred; solid lines are drawn where the contacts are either visible at road level or easily identifiable from aerial imagery. B) Google Earth perspective view (2× vertical exaggeration) of the stratigraphic section of the marine (M1–4) to fluvial (F1) transition along the Lengpui Airport road. Thicknesses were estimated based on elevations of mapped contacts due to subhorizontal dips.

Outcrop photographs showing example lithofacies characteristics from the Surma and Tipam groups. A) Outcrop exposure (left) and detail (right) of the M1 facies, interpreted as bottomset beds of the subaqueous delta. B) Outcrop scale (left), hand-sample scale (right), and thin-section image (center), of the M2 facies, interpreted as prograding foreset beds of the subaqueous delta. Note the hierarchy of scales, interpreted to represent oscillations in current strength from seasonal and/or monsoonal (cm-scale, right) to spring–neap (mm-scale, center). C) Outcrop exposure (left) and detail (right) of the M3 facies, interpreted as shallow shelf deposits in the subtidal to intertidal region. D) Outcrop (left and center) and detailed (right) view of the M4 facies, interpreted as tidal-channel deposits exhibiting large (m-scale) cross-bedding. The M4 facies is often found between shallow-shelf deposits of the M3 facies and fluvial facies of the F2 (left). E) Outcrop scale (left) and detail (right) of the F1 facies, interpreted as distributary channels of the lower delta plain. F) Outcrop (left and center) and detail view (right) of cross-bedded medium sands associated with F2 facies, interpreted as braidbelt sands of the Miocene–Pliocene Brahmaputra River. G) Outcrop (left and right) and detail view (center) of the multicolored F3 facies, representing deposition by small rivers draining local catchments.
