Cosmogenic Exposure Dating (³⁶Cl) of Landforms on Jan Mayen, North Atlantic, and the Effects of Bedrock Formation Age Assumptions on ³⁶Cl Ages

Geosciences, 2021
Jan Mayen is a small volcanic island situated 550 km north of Iceland. Glacial sediments and landforms are relatively common on the island but, so far, only a few of them have been dated.

Build-up and chronology of blue ice moraines in Queen Maud Land, Antarctica

Quaternary Science Advances, 2020
Blue ice moraines are common supraglacial landforms in Antarctica and they are considered to record the ice volume fluctuations. In this study, we use photogrammetry and the analysis of multiple cosmogenic nuclides (10Be, 26Al, and in-situ 14C) in ...

Holocene Earthquakes on the Tambomachay Fault near Cusco, Central Andes

Tektonika, 2023
A system of active normal faults around the city of Cusco have severely damaged the city in major earthquakes in pre-hispanic times, 1650 and 1950 CE. Detailed studies of these faults adjacent to Cusco are therefore needed to build an understanding of ...

Lichenometry dating of coseismic changes to a New Zealand landslide complex

Annals of Geophysics, 2003
Lichenometry is a surface-exposure-dating procedure that complements traditional trench-and-date stratigraphic studies of earthquakes. Lichens on the surficial blocks of a slump in the Seaward Kaikoura Range, South Island, New Zealand provide ...

Blue-ice moraines formation in the Heritage Range, West Antarctica: Implications for ice sheet history and climate reconstruction

Quaternary Science Advances, 2022
Blue ice is found in areas of Antarctica where katabatic winds, focussed by steep surface slopes or by topography around nunataks, cause enhanced surface ablation.

Effect of related parameters on exposure age and erosion rate obtained via rock surface luminescence dating

He jishu
BackgroundRock surface luminescence dating has developed rapidly in the past decade. It has been widely used to obtain exposure ages and erosion rates of various rocks in archaeology, geology, and geography, such as stone artifacts, glacier bedrock ...

Chlorine-36 Surface Exposure Dating of Late Holocene Moraines and Glacial Mass Balance Modeling, Monte Sierra Nevada, South-Central Chilean Andes (38°S)

Frontiers in Earth Science, 2022
The development of robust chronologies of Neoglaciation from individual glaciers throughout the high-altitude Andes can provide fundamental knowledge of influences such as regional temperature and precipitation variability, and aid in predicting future ...

Slope Failure in a Period of Increased Landslide Activity: Sennwald Rock Avalanche, Switzerland

Geosciences, 2021
The Säntis nappe is a complex fold-and-thrust structure in eastern Switzerland, consisting of numerous tectonic discontinuities and a range of hillslopes prone to landsliding and large slope failures that modify the topography irreversibly.
