Testing Luminescence Dating Methods for Small Samples from Very Young Fluvial Deposits [PDF]

, 2019
The impetus behind this study is to understand the sedimentological dynamics of very young fluvial systems in the Amazon River catchment and relate these to land use change and modern analogue studies of tidal rhythmites in the geologic record.

Preliminary Study on Al2O3:C Optically Stimulated Luminescence Dosimeter

Journal of Isotopes, 2021
Al2O3:C optically stimulated luminescence dosimeter (OSLD) was prepared by liquid film forming method, and its dosimetric properties were studied. The results showed that the background was 0.03 mGy after annealing, the uniformity was better than 2%, and

THERMALLY-OPTICALLY-THERMALLY STIMULATED LUMINESCENCE

IJRDO-Journal of Applied Science, 2023
A three-stage energy band model was studied. The model consists of electrons thermally stimulated from the ground state to the first excited state, after which they were optically stimulated into the second excited state and they were finally stimulated thermally into the conduction band.

Terrace reconstruction and long profile projection: a case study from the Solent river system near Southampton, England [PDF]

, 2012
River terrace sequences are important frameworks for archaeological evidence and as such it is important to produce robust correlations between what are often fragmentary remnants of ancient terraces.

Anomalous luminescence of subglacial sediment at Haut glacier d'Arolla, Switzerland - a consequence of resetting at the glacier bed? [PDF]

, 2010
<p>Luminescence has the potential to elucidate glacial geomorphic processes because primary glacial sediment sources and transport pathways are associated with contrasting degrees of exposure to light.

Combining bulk sediment OSL and meteoric 10 Be fingerprinting techniques to identify gully initiation sites and erosion depths [PDF]

, 2017
Deep erosional gullies dissect landscapes around the world. Existing erosion models focus on predicting where gullies might begin to erode, but identifying where existing gullies were initiated and under what conditions is difficult, especially when ...
