Abstract

Bathymetric and single-channel seismic data from the upper and middle part of the Indus Fan reveal three major seismic units: (1) an extensively faulted acoustic basement, probably of oceanic origin in the southwest and of continental origin in the northeast. In the northeastern areas, the basement is overlain by an eroded cover probably of sedimentary or volcano-sedimentary nature; (2) an overlying infilling unit, inferred to consist partly of distal turbidites; and (3) the Indus Fan proper. The fan is divided into five depositional sequences, each composed of several channel-levee complexes. Examination of their seismic facies suggests that the construction of the fan was controlled by the combined effect of (1) eustatic fluctuations, (2) tectonic history of both the source regions (Himalayas) and receiving basin (Arabian Basin), and depositional paleomorphology. During the evolution of the fan, the depositional areas displayed both lateral and longitudinal shifts. The result of these displacements is an eastward and basinward migration of deposition. The initiation of fan-type sedimentation in the Arabian Basin is related to the initial formation of canyons on the shelf and slope, and probably occurred some time after the first emergence of the Himalayan Ranges during the early to late Oligocene.
