Khasi Hills area of Meghalaya, one of the highest rainfall zones of the world has been explored to understand the spatial and temporal extent of Quaternary sediments. In general such deposits are restricted to shallow depths in most of the sites except in one site where it is 600 cm thick. AMS C-14 dates of these deposits suggest that sediments deposited are mostly of Holocene or in rare cases belong to later part of Pleistocene. Early Quaternary deposit is either missing or yet to be explored from this region. Natural hazards combined with human activity effecting degradation of vegetation and sediment cover are probably the main cause for poor Quaternary exposure at the region.

Abstract


Khasi Hills area of Meghalaya, one of the highest rainfall zones of the world has been explored to understand the spatial and temporal extent of Quaternary sediments. In general such deposits are restricted to shallow depths in most of the sites except in one site where it is 600 cm thick. AMS C-14 dates of these deposits suggest that sediments deposited are mostly of Holocene or in rare cases belong to later part of Pleistocene. Early Quaternary deposit is either missing or yet to be explored from this region. Natural hazards combined with human activity effecting degradation of vegetation and sediment cover are probably the main cause for poor Quaternary exposure at the region.
