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 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.

在扫描电镜下对昆仑山垭口地区的现代冰碛、古冰碛、现代冰水沉积、古湖滨河流三角洲沉积和冲洪积扇沉积中的石英砂表面结构进行了观察,显示出不同沉积环境下的石英砂表面特征组合有着显著的差别,尤其是冰碛物中石英砂表面特征组合的特殊性为鉴别古冰碛和其它混杂堆积提供了有力的证据。同时也指出,石英砂表面特征不仅反映着最终的沉积环境,而且也包含着一系列的沉积历史过程。

The texture mapping in Computer Graphics have been discussed in the paper. Based on the surface texture characteristics of real objects, three mapping methods are given in the paper. Surface texture mapping algorithm based B-splint parameter surface, and bump mapping algorithm based surface voter twist to produce real objects sense are suggested. Solid mapping method is also introduced in the paper.
