The deep accumulation of 10Be at Utsira, southwestern Norway: Implications for cosmogenic nuclide exposure dating in peripheral ice sheet landscapes

open access: yesGeophysical Research Letters, 2016
Cosmogenic nuclide exposure dating is a widely used method for constraining past ice sheet histories. We scrutinize a recently published data set of cosmogenic 10Be data from erratic boulders in Norway used to constrain the deglaciation of the western ...

Autochthonous Micrite to Aphanodolomite: The Microbialites in the Dolomitization Processes

open access: yesGeosciences, 2018
In the present paper, we examine the influence of micrite types, autochthonous or allochthonous, on the dolomitization processes. The recrystallized and dolomitized Carnian samples from Rifugio Vallandro and Alpe di Specie erratic boulders (South Tyrol ...

Surface geometry of the Last Glacial Maximum (LGM) in the southeastern Swiss Alps (Graubünden) and its paleoclimatological significance [PDF]

open access: yesEiszeitalter und Gegenwart, 1998
Using detailed field evidence provided by trimlines on former nunataks, erratic boulders and the orientations of glacial striae, the surface geometry in the accumulation area during the Last Glacial Maximum was reconstructed for the area of SE ...

VIII. Description of an Erratic Boulder on the Highland Railway [PDF]

open access: yesTransactions of the Geological Society of Glasgow, 1883
A CONSIDERABLE number of years ago, when our Society was young, and the story of glacial phenomena was foremost in our minds, my attention was attracted by a large boulder conspicuously exposed near the embankment of the Highland Railway, about 500 yards south of the Dalwhinnie station, on the Loch Ericht side, or the left side going north.

A regional assessment of the deglaciation history of the Swiss Plateau based on newly obtained and re-evaluated Be-10 cosmic-ray exposure ages

open access: yesQuaternary Science Advances
During marine oxygen isotope stage (MIS) 2, the Swiss Plateau temporarily hosted large piedmont lobe glaciers that retreated after their maximum advance back to the fringe of the Alps.
