Surface Dating of Dynamic Landforms: Young Boulders on Aging Moraines

Science, 1994
The dating of landforms is crucial to understanding the evolution, history, and stability of landscapes. Cosmogenic isotope analysis has recently been used to determine quantitative exposure ages for previously undatable landform surfaces. A pioneering application of this technique to date moraines illustrated its considerable potential but suggested a

Investigating the resetting of IRSL signals in beach cobbles and their potential for rock surface dating of marine terraces in Northern Chile [PDF]

Marine Geology, 2022
Inactive shorelines represent valuable records for sea level change, shoreline variations and tectonics if we can constrain the timing of their formation.

OPTICAL DATING OF GRANITIC STONE SURFACES*

Archaeometry, 2005
A novel luminescence methodology for dating surfaces of granitoid rocks is presented, with encouraging results for archaeological stone structures. It is based on the zeroing of the latent signal of optically stimulated luminescence (OSL) in feldspar and quartz grains of the stone surface during exposure to daylight.

In Situ Radiometric and Exposure Age Dating of the Martian Surface

Science, 2014
We determined radiogenic and cosmogenic noble gases in a mudstone on the floor of Gale Crater. A K-Ar age of 4.21 ± 0.35 billion years represents a mixture of detrital and authigenic components and confirms the expected antiquity of rocks comprising the crater rim. Cosmic-ray–produced 3 He, 21
