Abstract:

L'objectif de cette étude est d'évaluer la part de l'empreinte glaciaire dans les paysages de la haute montagne aux latitudes moyennes. Peut-on transposer au Quaternaire la très grande efficacité de l'érosion glaciaire mesurée actuellement dans certaines montagnes et faire de cet agent le principal acteur de la morphogenèse ? Doit-on au contraire constater une forte résilience des paléoformes tertiaires et donc la faiblesse relative de l'érosion glaciaire ? Le domaine est-pyrénéen offre un terrain privilégié en raison du fort contraste nord-sud qui caractérise l'emprise spatiale et l'impact gé

Abstract:

During the last main phase of glaciations (26-13kaBP) an ice cap developed in south west Ireland and ice, from a dispersal centre in the vicinity of Kenmare, flowed north and diverged on the southern slopes of the Macgillycuddy’s Reeks. On these slopes, a weathering limit separates ice-moulded bedrock, on low ground, from frost-weathered terrain above. Assessment of bedrock dilation joint characteristics, Schmidt hammer R-value data, clay-sized mineral contents and magnetic properties of basal soil samples confirms significant contrasts in the degree of weathering above and below this limit.

This thesis develops a better knowledge of the extent and timing of glaciations in southern Argentina throughout the Quaternary. It provides a detailed understanding of successive major glacial outlet lobes in the Lago Pueyrredón valley. The glacial and glaciofluvial deposits in the valley, as elsewhere in the region, are extremely well-preserved and reflect punctuated glacial advances between ~ 1.1 Ma and ~ 17 ka. Several intermediate glaciations are undated, constrained by the limited time frame of radiocarbon age dating, the limited potential volcanic sites for K-Ar or 40Ar/39Ar age dating,

Two vegetation types were alternately dominant: thermophilous forests and open vegetations including Artemisia steppes. During the Late Miocene, most of the tropical and subtropical plants declined because of the climatic deterioration. However, some of them survived during the Late Pliocene, such as those

Despite considerable active research in the realm of Quaternary studies in Scotland, some parts of the Scottish Highlands remain largely uninvestigated in terms of both glacial and environmental history.

Several attributes of the last British-Irish Ice Sheet (BIIS) make it a potentially important analogue to marine-based sectors of modern ice sheets, which are sensitive to oceanic and climatic changes and unstable during the current global climate warming. However, limitations on knowledge of the last BIIS's marine termini hinder the use of this ice mass in comparative assessments or modelling. This research addresses this critical knowledge gap through multiproxy examinations of BIIS marine landforms, sedimentation and ice-proximal palaeoenvironments.

The timing and extent of former ice sheet fluctuations can demonstrate leads and lags during periods of climatic change and the forcing factors responsible, but this requires robust glacial chronologies. Patagonia, in southern South America, offers a well preserved record of glacial geomorphology over a large latitudinal range that is affected by key climatic systems in the Southern Hemisphere, but establishing the timing of ice advances has proven problematic.

The Late Saalian astronomical forcing was different than during the LGM while greenhouse gas concentrations were similar. To understand how this ice sheet could have grown so large over Eurasia during the Late Saalian, we use an Atmospherical General Circ
