Cosmogenic helium signatures at Deception Island volcano (Antarctica): geochronological implications for its eruptive history [PDF]

Scientific Reports
Cosmogenic nuclei production for dating the Earth surface exposure of rock/mineral samples, especially 3He, is a robust technique in geochronology. We describe its application to constrain the ages of key eruptive episodes of the volcanic history of ...

Inferring the timing of abandonment of aggraded alluvial surfaces dated with cosmogenic nuclides [PDF]

Earth Surface Dynamics, 2019
Information about past climate, tectonics, and landscape evolution is often obtained by dating geomorphic surfaces comprising deposited or aggraded material, e.g. fluvial fill terraces, alluvial fans, volcanic flows, or glacial till.

Quantification of post-glacier bedrock surface erosion in the European Alps using ¹⁰Be and optically stimulated luminescence exposure dating [PDF]

Earth Surface Dynamics, 2022
The retreat of glaciers since the Last Glacial Maximum in the European Alps has left an imprint on topography through various erosional processes. However, few methods are currently capable of resolving these mechanisms on Late Glacial to Holocene ...

Cosmogenic ³He and ²¹Ne Dating in Accessory Mineral Phases [PDF]

, 2010
The development of terrestrial cosmogenic nuclide dating has led to applications as varied as the dating of glacial moraines, establishing slip-rates on faults, measuring the erosion rates of basins, and measuring rates of soil formation.

Piecing together the Lateglacial advance phases of the Reussgletscher (central Swiss Alps) [PDF]

Geographica Helvetica, 2018
Exposure dating has substantially improved our knowledge about glacier advances during the Younger Dryas (YD) and the early Holocene. The glacier development after the Last Glacial Maximum (LGM) and the timing of morphologically evidenced, earlier ...

New technique for surface exposure dating [PDF]

Eos, Transactions American Geophysical Union, 2012
A new technique that allows researchers to determine the amount of time a rock sample has been exposed to daylight could find many applications in geology and archaeology. The new method, pioneered by Sohbati et al., is based on optically stimulated luminescence (OSL) bleaching profiles.

The late Quaternary slip-rate of the Har-Us-Nuur fault (Mongolian Altai) from cosmogenic Be-10 and luminescence dating [PDF]

, 2009
The Altai range (western Mongolia) accommodates NNE–SSW shortening across the northern India–Eurasia collision zone by dextral slip on faults trending NNW–SSE, and anticlockwise, vertical-axis rotations of fault-bounded blocks.

Glacial geomorphology of the Strait of Magellan ice lobe, southernmost Patagonia, South America

Journal of Maps, 2020
We present a geomorphic map of the landforms created by the Patagonian Ice Sheet during the local Last Glacial Maximum and perhaps prior glaciations in southernmost Patagonia. Building on prior work, the new mapping focuses in unprecedented detail on the

Terrestrial cosmogenic nuclide bedrock depth profiles used to infer changes in Holocene glacier cover, Vintage Peak, southern Coast Mountains, British Columbia [PDF]

Geochronology
The majority of glaciers in North America reached their maximum Holocene downvalley positions during the Little Ice Age (1300–1850 CE), and in most cases, this expansion also destroyed earlier evidence of glacier activity. Substantial retreat in the 20th
