... hypothesis involves the connection of the palaeo Tsangpo drainage to a precursor to the Irrawaddy River of central Myanmar in the Palaeogene. To test this hypothesis, we studied the provenance of Palaeogene fluvio-clastic sedimentary rocks that crop out in central Myanmar, namely the Late Middle Eocene–Early...

Along this terrace the bottom drops to the topographically complex basin floor with a maximum depth of 4,400 meters east of the Andaman-Nicobar Ridge. Principal sediment source for the basin is the load of the Irrawaddy River, estimated during...

... is the proper boundary between the Andaman-Nicobar Ridge and the Central Andaman Trough. Sediments in the Central Trough are 1.5 km thick, surprisingly thin in view of the huge Irrawaddy River sediment load which enters the north end of the basin and is trapped in the basin by surface currents. Large volumes...
