Relict fluvial and lacustrine deposits in the interior of Oman near Saiwan consist of waterlain brecciaswith pebble imbrications and current ripples, covered by algal laminites containing calcified reeds and charcoalpieces. Geomorphological evidence suggests that the palaeolake covered a maximum surface of 1400 km2 and had amaximum depth of about 25 m. Optically stimulated luminescence (OSL) and thermally transferred OSL datingindicate that this palaeolake existed sometime between 132 and 104 ka. The rich archaeological evidence in the areasuggests substantial human occupation, possibly at the time when Palaeolake Saiwan existed. Interestingly, the lithictraditions of the archaeological material show no clear relation to coeval findings from neighbouring areas, putting aquestion mark on the origin of the culture found at Saiwan. This finding raises questions concerning the origin of thepopulation inhabiting Saiwan, as the site lies along one possible route for the dispersal of anatomically modern humansout-of-Africa.
