Reflection of the glacial-intergalcial cycle in the evolution of the Vistula River basin, Poland

Reflection of the glacial-intergalcial cycle in the evolution of the Vistula River basin, Poland
Fluvial processes ; Glacial features ; Interglacial ; Poland ; Quaternary ; Valley ; Valley floor evolution ; Watershed ; Wisła
A variety of factors include climatically induced changes of the river runoff and sediment load, glacial advances and rapid variations of the base level, as well as the influence of the tectonic factor. The first-order climatic cycles are reflected
in separate terrace fills. The second-order fluctuations may be represented by separate cuts and fills, by the change of the facies or in the granulometric composition. The analysis of the changes in the longitudinal profile helped to discover different valley

Fluctuations of outlet and valley glaciers in the Southern Andes (Argentina) during the past 13,000 years

Fluctuations of outlet and valley glaciers in the Southern Andes (Argentina) during the past 13,000 years
Andes ; Argentina ; C 14 dating ; Climatic variation ; Glacial features ; Glacier advance ; Holocene ; Lateglacial ; Palaeo-environment
In the southern Argentine Andes, ten advances of valleys glaciers were used to reconstruct the late-glacial and Holocene glacier history. The accumulation areas of these glaciers lie in the Precordillera and are thus independent of fluctuations
of the South Patagonian Icefield (SPI). This paper discusses the number, age, and extent of these valley glacier advances during the late-glacial and postglacial intervals.

Early Pleistocene glacial Lake Lesley, West Branch Susquehanna River valley, central Pennsylvania

Early Pleistocene glacial Lake Lesley, West Branch Susquehanna River valley, central Pennsylvania
Dating ; Fluvioglacial features ; Geochronology ; Glacial features ; Palaeo-environment ; Palaeomagnetism ; Pennsylvania ; Pleistocene ; Proglacial lake ; Stratigraphy ; United States of America
The AA. use new exposures in the West Branch Susquehanna River (WBSR) valley and magnetostratigraphy to reconstruct depositional environments in Glacial Lake Lesley, constrain the age of Glacial Lake Lesley, and constrain the maximum extent
of Glacial Lake Lesley. To achieve these objectives, detailed stratigraphic sections were described at McElhattan and Linden. The AA. use paleomagnetism as an age correlation tool in the WBSR valley to correlate contemporeanous glaciofluvial and proglacial

Paleomagnetic evidence for repeated glacial Lake Missoula floods from sediments of the Sanpoil River valley, northeastern Washington

Paleomagnetic evidence for repeated glacial Lake Missoula floods from sediments of the Sanpoil River valley, northeastern Washington
Recent explanations of widespread rhytmically layered sediments in eastern Washington as the result of repeated great floods from glacial Lake Missoula implicitly suggest a paleomagnetic test for validity. This work is an application

A model of late Quaternary landscape development in the Delaware Valley, New Jersey and Pennsylvania

A model of late Quaternary landscape development in the Delaware Valley, New Jersey and Pennsylvania
Colluvium ; Erosion ; Geochronology ; Geomorphogenesis ; Glacial features ; Model ; Oxygen 18 ; Pedogenesis ; Periglacial features ; Quaternary ; United States ; Wisconsinan
This paper proposes a chronologic model for late Quaternary nonglacial events, and relates them to glacial episodes in the Delaware Valley of eastern Pennsylvania and northwestern New Jersey.

that they were eroded by groundwater seeps fed by proglacial lakes dammed by the outwash plains and associated moraines. Valley erosion terminated after the lakes were drained and the water table dropped.

Connection between geomorphology and vegetation in glacial valley on the example of Pisia Valley in central Poland in Végétation et géomorphologie.

Connection between geomorphology and vegetation in glacial valley on the example of Pisia Valley in central Poland in Végétation et géomorphologie.
On the basis of geomorphological-petrographical research, analysis of grain-size distribution and processing of quartz particle analysis, the morphogenesis of the valley was determined. The influence of relief into development of soil-forming types

Detailed investigations of sediment transport have been carried out in a proglacial valley at the Mitdluagkat Glacier in East Greenland. The results from 1989, 1990 and 1991 have been compared with earlier measurements of sediment transport

The fluvial factor in the evolution of alpine valleys and of ice-marginal topography in Vorarlberg (W-Austria) during the Upper Pleistocene and Holocene

The fluvial factor in the evolution of alpine valleys and of ice-marginal topography in Vorarlberg (W-Austria) during the Upper Pleistocene and Holocene
Austria ; Fluvial processes ; Fluvial terrace ; Geochronology ; Geomorphogenesis ; Glacial features ; Glaciation ; Mountain ; Palaeoclimatology ; Palaeogeography ; Quaternary ; Snow line ; Valley ; Vorarlberg
This paper illustrates the significant role of fluvial processes through time, in a key sector of the northern Alps. Emphasis is put on the interaction between fluvial and glacial processes during the Upper Pleistocene and on the related glacial
and postglacial development of valley systems. The morphology of mixed-type valleys is highly persistent, as it had developed before and was maintained during the Upper Pleistocene. The topographic position of these valleys and their fills can be used

Analysis of flute forming conditions using ice sheet reconstructions and field techniques

Canada ; Cold area ; Glacial erosion ; Glacial features ; Ice sheet ; Palaeogeography ; Saskatchewan ; Shear stress
Basal shear stress and sediment strength associated with the development of glacial flutes exposed during the 20th century in the Saskatchewan Glacier Valley Alberta, Canada, were determined by comparing reconstructed ice thickness, basal shear
stresses, and field properties of sediments with the morphologically similar Kiwa Glacier Valley, British Columbia, Canada, where flutes are absent. Reconstructed subglacial conditions in these 2 valleys were compared to understand why flutes were developed

The morphological development of alpine valley heads in the Antarctic Peninsula
Antarctica ; Cirque ; Cold area ; Earth surface processes ; Geomorphometry ; Glacial features ; Glacial valley ; Glaciation ; Model
Glaciation has continued in Antarctica for longer than anywhere else on Earth, so the long-term development of glaciated landforms can be investigated. This study is based on a morphometric analysis of the plan form of 1680 alpine valley heads
