| Abstract: | The quartz sand grains from the modern till, palaeo-till, modern glacio-fluvial sediment, palaeo-lakeside delta deposit and fluvio-diluvial fan in the region of Kunlun Shan Pass were examined under Electronic Scanning Microscope for their external morphological characteristics. The combination of different surface texture characteristics and indicated sedimentary environments were discussed and discerned. The combination of specific surface texture characteristics of quartz sand from the till provide a powerful evidence for distinquishing between palaeo-till and other non-glaciogenous diamictons. It is also pointed that the surface characteristics of quartz sand not only represent its final sedimentary environment, but also include a series of depositional processes. |
