在考察天山大西沟冰川的侵蚀堆积规律过程中,同时对高山寒冻地区公路的选线工程地质问题以及岩石风化剥蚀的速率作了一些调查研究。 研究地段选择在跨越冰达板3号冰川北侧哑口的废弃公路(1959年弃用)。该处的地层为志留系阿河布拉克组,岩性为各种结晶片岩、片麻岩。由于受近南北向的挤压力的作用,形成近东西走向的高倾角岩层,并有冰达板断层和大量X节理的发育,绢云母石英片岩被切割成菱块状,经寒冻风
In the course of examining the erosion and deposition of the Daxigou glacier in the Tianshan Mountains, some investigations were made on the engineering geological problems of route selection and the rate of weathering and denudation in the alpine frozen area. The study site was chosen to be an abandoned highway that straddled the northern side of Icebergs Glacier No. 3 (abandoned in 1959). The stratum here is the Silurian Aheburak Formation, with lithology of various crystalline schist and gneiss. As a result of the nearly north-south crushing force, a high-dip strike-to-east strike rock formation is formed. With the development of the ice-plate fault and a large number of X-joints, the sericite quartz schist is cut into blocks,
