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
Through the interpretation of sedimentological, geomorphological, paleoclimatic and tectonic information the geomorphic evolution of the Transdanubian Mountains from the Cretaceous to the Quaternary is presented. Several sedimentary cycles occurred
in the range governed by alternating uplift and denudation. Intervals of valley incision and of planation of various type have been identified. At the beginning of the Quaternary pedimentation was the principal geomorphic factor, then replaced by fluvial
The AA. examined the stepped geomorphic surfaces of foreland eastern Qilian Shan, which were chronologically constrained by a combination of new dates from palaeomagnetism, ESR, TL, IRSL and radiocarbon dating. From these new dates, they aim to gain
new insights into the evaluation of tectonism and climatic changes as the 2 major terrace-forming factors in the context of episodic uplift of Tibetan Plateau. The repetitive stratigraphic and geomorphic pattern of these terraces indicates the fluvial
sedimentation-incision cycles are tightly associated with the 100-ka glacial-interglacial climatic cycles.

In the last two-three decades the majority of Czech geographers and geomorphologists is taking a negative standpoint towards the theory of the geomorphological cycle of W. M. Davis. The present article shows their unfavourable impact

This paper presents field observations on present-day geomorphic processes in a snowpatch hollow on Gassan volcano, a remarkably snowy mountain in northern Honshu. The measured variables include soil temperature, debris production from rock surface

The principal objective of this paper is the determination of geomorphic work accomplished by rockglaciers in the Khumbu Himalaya, and to compare this work with rates obtained in continental mountain ranges of the mid-latitudes.

Problems of cyclicity exist in all spacio-temporal scales accessible to science. Planetary, solar and galaxical cycles are considered within the range of 109 years which are recorded by geological and biological indicators. Possibilities of long

Biographie du géomorphologue Henry Baulig (1877-1962) qui a étudié avec Davis entre 1905 et 1911. Il a adopté la théorie du cycle géomorphologique mais a aussi donné un rôle important à l'eustatisme. Dans son oeuvre, on remarque particulièremment
Quelques types de systèmes d'érosion-accumulation avec un cycle d'évolution fermé sont définis et décrits: cours d'eau - lacs, cours d'eau permanent - delta intérieur (champ d'épandage), cours d'eau temporaire - cône de déjection, cours d'eau - mer

This paper assesses current understanding of the relationship between glacierised landscapes and dust emissions and inputs to the global dust cycle. It focuses on how elements in the glacial and aeolian geomorphic sub-systems interact to determine

This paper summarizes a reconnaissance study of geomorphic response to the recent wet interval of 1978-1983 in interior regions of San Diego County. Understanding the effects of short-term, episodic changes in climate on landforms will permit
