The main aim of this paper is to examine geomorphic activity in the central Karakoram, between 3 000 and 6 000 m, where precipitation seasonally released meltwaters and freeze-thaw cycles are relatively abundant. Glacier ablation zones compose
Terraces, uplift and climate in the Karakoram Mountains, Northern Pakistan : Karakoram intermontane basin evolution in Quaternary of the Karakoram and Himalaya.
This paper concentrates on the Recent and Pleistocene sediments produced in the Karakoram glacial and paraglacial environments in terms of their sedimentological characteristics, landforms and the processes that produced them. Two main types
This paper reports on rock temperature fluctuation in the north and south surfaces of a moraine boulder in Hunza Karakoram obtained over 2 years, and concludes that the rock surface weathering processes depend primarily on the differences
Deux carottes de glace ont été prélevées du Glacier Qogir situé sur le versant Nord du Mont Qogir (K2), Karakoram, en automne 1986. Les échantillons ont été analysés : σD, σ18O, degré de minéralisation et pH. Les caractéristiques stratigraphiques et

This excellent study uses a diachronic approach to examine the transformations in the Hunza Valley. External interventions brought by the Karakoram Highway have changed the internal structure and economic conditions. Grazing high pastures has
Les transports en masse sont un processus majeur dans les vallées de Karakoram Mountains : chutes de blocs, avalanches, éboulements de débris et de pierres, creep, glissements rotationels, coulées de débris et flowsides. Une identification correcte
Botanical results of the « Sino-German Joint Expedition to K2, 1986 » are presented with remarks on vegetation of SW Kashgaria, the W Kunlun Shan and the N declivity of the central Karakoram mountains. The vertical and horizontal zonation
of the vegetation and flora of a cross-section of the Karakoram/Kunlun N declivity from the edge of the Tarim basin to the summit-pyramid of K2 is outlined. An annotated list of 301 species collected is given. Floristical and vegetation features of the Karakoram

The Karakoram terrane in Northern Pakistan is geologically equivalent to the Qiangtang terrane of central Tibet but unlike Tibet shows extreme topographic relief, high uplift-exhumation and erosion rates and exposes deep crustal metamorphic
and igneous rocks of the lower crust. The Karakoram terrane has been above sea-level since Early to Mid-Cretaceous, the age of the youngest marine sedimentary rocks. Geological and U-Pb geochronological data show that the Karakoram Range was a dynamic active
Observations on rock glaciers in the Himalayas and Karakoram Mountains of northern Pakistan and India
This paper will examine the characteristics and distribution of rock glaciers in the Karakoram Mountains and northern India to highlight importance as geomorphological agents and to assess geomorphological significance.
The AA. report new field observations on stratigraphy, sedimentology, and geochemical data of plutonic rocks of the Shyok suture zone separaring the Ladakh terane to the SW from the Karakoram terrane to the NE. Six tectonic units have been
Les formes latéro-glaciaires marquent profondément les paysages des montagnes du Karakoram pakistanais. Des glaciers longs de 60 km sont accompagnés de sédiments latéro-glaciaires de plusieurs dizaines de km. On les trouve entre 2500 et 5000 m

L'autoroute du Karakoram traverse une région montagneuse où l'activité géodynamique est très importante : tremblement de terre, érosion glaciaire, incision des rivières, action périglaciaire et moussons imprévisibles. La route subit donc constamment
A new geological map the central-western part of the Karakoram belt (Northern Areas and North West Frontier Province, Pakistan) is presented with its explanatory notes. The map is printed at a 1:100,000 scale, summarizing original field surveys
