In the Western Carpathians, clear evidence of Pleistocene glaciations only occurs in two mountain massifs – Tatra and Low Mountains. The Mountains (2043 m a.s.l.), contrary to higher more strongly glaciated (2654 have previously been much less attractive for scientific research. Hence, these mountains, both glacial landforms chronology, together with a detailed reconstruction glacier geometry r...
a r t i c l e i n f o a b s t r a c t The majority of martian valley networks are found on Noachian-aged terrain and are attributed to be the result of a 'warm and wet' climate that prevailed early in Mars' history. Younger valleys have been identified, though these are largely interpreted to be the result of localized conditions associated with the melting of ice from endogenic heat sources. S...
Titelbild: Starting zone of Kolka/Karmadon rock/ice avalanche in the Russian Caucasus (September 2002) showing Dzhimarai-khokh (4780 m a.s.l.) and the eroded Kolka glacier on the valley bottom (photo: I. Galushkin) I Summary Research on glacial hazards is challenged by current natural and human-induced and-related developments. Climate change strongly influences the dynamics in glacial and peri...
In the Obernberg valley, the Eastern Alps, landforms recently interpreted as moraines are re-interpreted as rock avalanche deposits. The catastrophic slope failure involved an initial rock volume of about 45 million m³, with a runout of 7.2 km over a total vertical distance of 1330 m (fahrböschung 10°). 36Cl surface-exposure dating of boulders of the avalanche mass indicates an event age of 8.6...
Late Neogene paleoceanographic history in the western North Pacific is discussed on the basis of: (1) Td (diatom temperature) values, (2) species composition, and (3) the structure of diatom assemblages at Sites 579 and 580. These factors provide a record of fluctuations of the past position of the subarctic-subtropic front because these sites lie within the transition zone between the modern d...
In tectonically active mountain ranges, the landscape is shaped by interplay of erosion/sedimentation and driven crustal deformation. Characteristic landforms such as moraines, wind gaps, fault scarps, river terraces can be used to decipher evolution. However, available data often allow for different interpretations. Here we study Pradol (Pradolino) Valley in Western Slovenia, a deeply incised ...
