Luminescence Dating of Medieval and Early Modern Brickwork
… presented an opportunity to apply the scientific dating technique of optically stimulated luminescence in order to derive absolute dates for important medieval brick sites in Essex. This in turn would allow this framework of understanding surrounding medieval brick to be critically examined and …

Luminescence dating of Scottish burnt mounds: new investigations in Orkney and Shetland
This thesis presents new research on the luminescence dating of burnt mounds in the Orkney and Shetland Islands. Through an examination of available evidence for Scottish burnt mounds, a number of key problematic areas have been identified in relation to our understanding of these sites and their …

Development of techniques for high-resolution spatially-resolved elemental analysis in materials of interest in luminescence dating
… in support of current and future research in luminescence dating techniques. Under certain circumstances, sample heterogeneity, with respect to naturally occurring radionuclides, may significantly reduce the levels of accuracy associated with experimentally determined luminescence dates. The …

Ceramic building materials in early medieval churches in north-western France and south-eastern England. Application of luminescence dating to building archaeology.
Amongst the dating methods that can contribute to building archaeology, it is the technique of stimulated luminescence applied to ceramic building materials (CBM) that is the focus of this study. The research reported in this thesis concerns the re-evaluation of an archaeological assumption …

Exploration and application of post-infrared high-temperature infrared stimulated luminescence dating techniques: investigation of marine terrace deposits along the northern San Andreas Fault
Optically stimulated luminescence (OSL) dating is a relatively new dating method, tangibly introduced in 1985 when Huntley et al. demonstrated the ability to use light-sensitive traps to measure radiation exposure and determine the age of sediment. Quartz and feldspar grains are commonly used for …

Investigations of the geomorphologic and pedologic system of sedimentary vega deposits from Lanzarote (Canary Islands) supported by luminescence dating – important steps towards their palaeoclimatic interpretation
… we built up a chronostratigraphy using different luminescence-methods (quartz coarse- and fine grain-OSL, polymineral fine grain-IRSL). Fundamental investigations on the bleaching-behaviour of recent Saharan dust and colluvial sediments on Lanzarote demonstrate, that in spite of partial …

Investigating rates and mechanisms of lateral erosion in a small bedrock river using erosion pins, structure-from-motion photogrammetry, and optically stimulated luminescence dating: Konza Prairie, northeast Kansas
… channel banks. Single-grain optically stimulated luminescence (OSL) dating of fluvial deposits overlying a strath terrace was used to determine the depositional age of fluvial deposits and infer the duration of lateral channel mobility during terrace occupation. Lateral erosion rates of limestone …

Ανασύνθεση παλαιοπεριβάλλοντος σε παράκτιες γεωμορφές της νότιας Κύπρου με την χρήση τεχνικών φωταύγειας
Absolute dating methods have been developed during the last five decades (Jull and Scott, 2007). The most common methods applied to minerals’ dating are cosmogenic radionuclides, Electron Spin Resonance (ESR) and luminescence techniques. The latter were initially used to date burned minerals from …

Alternatives to Charcoal for Improving Chronometric Dating of Puget Sound Archaeological Sites
Radiocarbon dating of archaeological sites in the Puget Lowlands can be problematic. Dating specific cultural events associated with features and sites is difficult due to the ubiquity of charcoal in forest soils and poor preservation of bone in acidic soils. These conditions have impeded the …

Luminescence based chronologies on Late Pleistocene loess-palaeosol sequences: an applied-methodological study on quartz separates
… of such records has to be revealed by numerical dating. Luminescence dating, especially optically stimulated luminescence (OSL), is the leading dating approach for establishing chronologies on loess archives. Furthermore, the development of luminescence dating techniques on sediments is closely …

Geological recognition of abrupt marine invasions in two coastal areas of Portugal
… analysis and 210Pb and Optically Stimulated Luminescence dating. The investigated areas (e.g. Lagoa de Óbidos (Central Portugal) and Martinhal (South Portugal)) were affected by the AD 1755 tsunami. The locations have similar geomorphological features and are both susceptible to major abrupt …

Computer modeling and experimental work on the astrobiological implications of the martian subsurface ionising radiation environment
… and calibration of the optically stimulated luminescence dating technique, as a function of depth. The model predicts a population of radiation resistant cells to survive in martian permafrost soil for 450,000 years at 2 m depth, the proposed drill length of the ExoMars rover. The Antarctic …

Landscape forcing mechanisms on Quaternary timescales: The Tabernas Basin, SE Spain
… were obtained from Optically Stimulated Luminescence dating. Age estimations develop a pattern of climatically driven terrace aggradations during glacial phases throughout the Middle to Late Pleistocene. This pattern fits well with regional models of enhanced terrace formation during …

Tectonic-erosion interactions : insights from the paleo-drainage of the Brahmaputra River
… in the foreland basin. Sediment depositional dating of two sedimentary sections is performed using magnetostratigraphy, apatite fission-track and luminescence dating. Provenance analysis using zircon and apatite U-Pb dating allows the reconstruction of the Miocene-Quaternary paleo-drainage of …

Active Faulting in the Northern Walker Lane and Post-Earthquake Reconnaissance in the Central Walker Lane, Nevada and Eastern California
… of earthquake events. Optically stimulated luminescence dating methods were applied to faulted alluvial fan deposits exposed in the trench. For the Bonham Ranch fault, Uncrewed Aerial Vehicle (UAV) flight surveys were conducted in three locations to investigate differences between …

Exploring Long-Term Flood Variability in the Lower French Broad River Using Fluvial Paleoflood Hydrology
… age-depth model using long optical stimulated luminescence dating of quartz and radiocarbon-dated wood from distinct flood units was used to estimate paleoflood ages. Particle size data was statistically analyzed to identify "flood peaks" using End-Member Analysis and Locally Estimate …

The palaeolithic of the Avon valley: a geoarchaeological approach to the hominin colonisation of Britain.
… main Palaeolithic sites. Optically stimulated luminescence dating of fine-grained sediments from a sequence of six different terraces is used to create a chronometric framework for landscape evolution and the archaeological record. The results indicate that hominins were present in the Avon …

Eolian Landscape History and Prehistoric Dune Farming in Petrified Forest National Park: A Geoarchaeological Approach to Understanding the Long-Term Use of a Marginal Landscape
… geomorphic analysis and optically stimulated luminescence dating document discrete periods of eolian activity in the study area. The oldest eolian activity dates to ca. 16,000–11,000 B.C., and is expressed as stable dunes on upland landscape positions. Extensive remobilization and deposition …
