Sedimentology, mineralogy and geochemistry of ooid sand beds in deep sea gravity cores (water depth >2818 m) reveal that they were derived from continental shelf by turbidity currents. The presence of ooid turbidites at two different levels suggests two periods of turbidity current activity. The first activity probably took place during the Last Glacial Maximum in Late Pleistocene and the second activity prior to the stabilization of sea level in the Early Holocene.Keywords

During the course of mapping of active faults in the northwestern Outer Himalaya (using CORONA photographs, multispectral satellite data of Indian Remote Sensing satellite (IRS) and aerial photographs) we have identified an isolated basin of Quaternary and Holocene sediments resting unconformably on Siwaliks, around Parduni, in the northwestern Dehra Dun (Doon) valley. The region around Parduni is tectonically very complex and is traversed by active thrust faults to its north and south and strike slip faults to its east and west. The uplift and southward shift along the strike slip faults on both sides and the Markanda thrust edging to its south, the Parduni has developed as an intradun basin and now remains isolated from the main Doon valley. Based on the OSL age data widespread deposition of Quaternary alluvial fan sediments, the dun gravels, is inferred to have initiated around 34 ka BP in the western part of the Doon valley, while the sedimentation in the Parduni Basin started only around 27 ka BP, which more or less ceased around 20 ka. The southward movement of the Parduni Basin as a piggyback basin is ongoing with recent alluvial deposits covering the dun gravels tectonically overlain by the Siwalik sandstone and mudstones in the hanging wall of the Markanda thrust. The present communication discusses the development and evolution of the Parduni Basin vis-a-vis the configuration of the Doon valley in the northwestern Outer Himalaya and the prevalence of tectonics expressed or demonstrated in the active Himalayan Front.Keywords
