ABSTRACT

This paper presents a new geomorphological map for the lower Hushe Valley (below 3400 m asl), located to the SE of the Central Karakoram in Baltistan (North Pakistan). Fieldwork and remote sensing were combined to improve understanding of the most recent surface landforms to produce a 1:50,000 scale map. Thirteen landform types associated with glacial, fluvial, gravitational and mass wasting processes were identified and mapped. Particular emphasis was made on currently dynamic processes that could pose a threat to the population. The distribution of the landforms on the valley (reworked tills, alluvial fans, rockfalls, among others) differs between the eastern and the western hillslopes, and from north to south, mainly due to bedrock types, location of geological structures and distribution of lateral tributaries. This map is the first and necessary step towards a deep assessment on geological risk related to external processes in the area.

摘要

本文介绍了位于巴尔蒂斯坦（巴基斯坦北部）中部喀喇昆仑山脉东南部的胡舍河谷下游（海拔3400 m以下）的新地貌图。野外工作和遥感相结合，以增进对最新地表地形的理解，从而制作出1：50,000比例尺的地图。识别并绘制了与冰川，河流，引力和消瘦过程相关的13种地貌类型。特别强调当前可能对人口构成威胁的动态过程。东部和西部山坡之间以及从北到南的山谷地貌分布（重做的耕作，冲积扇，落石等）都不同，这主要是由于基岩类型，地质结构位置和侧支流的分布。
