ABSTRACT

The deposition of sediments within the valleys and intermontane basins of the Karakoram mountains is complex, dominated by the glacial and mass movement processes. Valley fills and terraces reach many hundreds of metres in thickness comprising till, glaciofluvial, glaciolacustrine, fluvial, debris-flow, flowslide, lacustrine and aeolian sediments. Holocene and Pleistocene sediments deposited in the Karakoram valleys and basins are described in terms of their sedimentological characteristics, their landforms and the processes that produced them. Six main sedimentary environments are recognized.
