How to Date Nothing With Cosmogenic Nuclides
Acta Carsologica, 2007 A cave is a natural void in the rock. Therefore, a cave in itself cannot be dated, and one has to resort to datable sediments to get ideas about the age of the void itself. The problem then is that it is never very certain that the obtained age really is

Application of in-situ produced terrestrial cosmogenic nuclides to archaeology: A schematic review [PDF]
Eiszeitalter und Gegenwart, 2008 The wide applicability of in-situ produced Terrestrial Cosmogenic Nuclides (TCNs) to geological problems and experiences in development and testing gained over the past decade is encouraging for its application to archaeological questions, where there is

Earth's Future, 2023 Land degradation resulting from increased continental surface erosion is a worldwide and systemic phenomenon due to unsustainable human activities. Already fragile, the intertropical zone is likely to be further affected by climate change like increased ...

Geosciences, 2021 We assess if variations in the in situ cosmogenic 26Al/10Be production ratio expected from nuclear physics are consistent with empirical data, knowledge critical for two-isotope studies. We do this using 313 samples from glacially transported boulders or

A zero-exposure time test on an erratic boulder: evaluating the problem of pre-exposure in Surface Exposure Dating [PDF]
Eiszeitalter und Gegenwart, 2009 The method of surface exposure dating using in-situ produced cosmogenic nuclides has become an important and widely applied tool in Quaternary science. One application is the dating of erratic boulders on moraines.

Journal of Space Weather and Space Climate, 2023 Cosmogenic nuclides – 14C from tree rings and 10Be and 36Cl from ice cores serve as an effective proxy for past extreme solar energetic particle (SEP) events.

Cratering and cosmogenic nuclides [PDF]
Geophysical Research Letters, 1975 A simple probabilistic model was constructed for the average value of a cosmogenic nuclide as a function of depth in a regolith. An arbitrary function was chosen for the size distribution of craters. The resulting integro‐differential equation was found to reduce in limiting cases to: 1) the marching equation with a characteristic residence time, and 2)

A decade of in situ cosmogenic 14C in Antarctica
Annals of Glaciology, 2022 Cosmogenic nuclide measurements in glacial deposits extend our knowledge of glacier chronologies beyond the observational record. The short half-life of in situ cosmogenic 14C makes it particularly useful for studying glacier chronologies, as resulting ...

Cosmogenic nuclide systematics and the CRONUScalc program [PDF]
Quaternary Geochronology, 2016 As cosmogenic nuclide applications continue to expand, the need for a common basis for calculation becomes increasingly important. In order to accurately compare between results from different nuclides, a single method of calculation is necessary. Calculators exist in numerous forms with none matching the needs of the CRONUS-Earth project to provide a ...

The potential of in situ cosmogenic 14CO in ice cores as a proxy for galactic cosmic ray flux variations [PDF]
The CryosphereGalactic cosmic rays (GCRs) interact with matter in the atmosphere and at the surface of the Earth to produce a range of cosmogenic nuclides. Measurements of cosmogenic nuclides produced in surface rocks have been used to study past land ice extent as ...
