Abstract

This paper describes Late Quaternary pedosedimentary sequences of the alluvial fans from the Kangra basin of NW Himalayas for tectonic and paleoclimatic implications. Formation of the loess in proximal and distal settings of the alluvial fans is related to the cool-dry climates during the advance of glaciers in the adjoining areas when climate was approaching towards the last glacial maxima. Field characters, micromorphology, grain size and clay minerals of these loessic deposits suggest strong pedogenesis of the loess during a warm-humid climate after the retreat of glaciers in the NW Himalayan region. The loess-paleosols show some degree of syndepositional pedogenesis in upper horizons and are accretionary in nature. Weakly expressed pedogenic features in fluvial and debris flow deposits suggest rapid sedimentation over unstable surfaces related to the reactivation of Main Boundary Thrust (MBT) and other regional faults
