Summary

This study describes the stratigraphical development of the Quaternary alluvial deposits in the Luni basin, Thar Desert of India. On the basis of mode of occurrence, lithofacies assemblages and overall alluvial motif, alluvial deposits have been differentiated into an older Type-1 and a younger Type-2 succession, with chronological control provided by optically stimulated luminescence dating. The Type-1 succession is composed of thick multistoreyed gravel–sand sheets and overbank heterolithic facies deposited in a subsiding basin by braided streams. Quartz in sediments of the Type-1 succession was in charge saturation, which implies a minimum age of 200 ka. It is argued that the Type-1 sequence was deposited during the Pliocene. The Type-2 succession consists of a diverse array of lithofacies assemblages that represents fluvial and aeolian depositional environments, which change in their relative importance through time. Optical ages from the Type-2 succession indicate deposition during the late Pleistocene and Holocene (oxygen isotope stages 5–1). The Type-2 succession indicates that high-amplitude climatic shifts during the last glacial cycle played a major role in determining the fluvial behaviour and resultant alluvial stratigraphy.
