Abstract: The landform development and Quaternary Glaciations in Northern Pakistan are of great significance to the Pleistocene Chronology and Geomorphology of High Asia. Based on the data collected during our visiting Pakistan in 1981, two main erosion surfaces are identified in the piedmont belt of the Himalayas. One is the Potwar Plateau, with an average elevation about 500 meters, and the other a dissected planation surface at an elevation about 1,600m above sea level They are progressively younger from north to south, ranging from 1.5 M. Y. B. P. to 0.4 M. Y. B. P. This reflects the southward expansion of the rising Hima-layas.
