The concept of open data has become the modern science meme, and major funding bodies and publishers support open data. On a daily basis, however, the open data mandate frequently encounters technical obstacles, such as a lack of a suitable data format for data sharing and long-term data preservation. Such issues are often community-specific and be...

Fossil coral reef terraces at the northern coast of Cuba in the vicinity of the Bay of Matanzas are forming a prominent flight of terraces. These terraces were already studied by several investigators, but a chronological classification based on numerical dating is still missing. In this study we focus on the lowest unit, the Seboruco terrace, whic...
Wave-transported boulders represent important records of storm and tsunami impact over geological timescales. Their use for hazard assessment requires chronological information on their displacement that in many cases cannot be achieved by established dating approaches. To fill this gap, this study investigated, for the first time, the potential of...

The work undertaken at the Jarama VI site (Valdesotos, Guadalajara, Spain) in the 1990s resulted in the recovery of thousands of archeological remains from the three Pleistocene sedimentary units of this cavity. Prior to the systematic analysis of the lithic material and the reception of new geochronological data, it had been suggested that the upp...

Over the past decades, optically stimulated luminescence (OSL) dating has become a key tool in the study of the Quaternary. It can provide absolute ages ranging from decades to several hundred ka using standard procedures. Despite the power of the technique, demand for extending the age range has increased, resulting in a large concentration of eff...
Until now, reliable chronological classifications based on numerical
ages for many Pleistocene fluvial deposits in the Alpine Foreland were rare.
In this study, new numeric data (ESR, OSL, 14C) from
Middle and Upper (Late) Pleistocene Hochterrassen
(high terraces) and
Übergangsterrassen (transitional terraces) in
the Bavarian Alpine Foreland are pr...
This study focuses on the accuracy of the Electron Spin Resonance (ESR) dating method applied to small land snail shells from eolian loess deposits, and from shell bearing clods of sandy loam and marl in fluvial gravel deposits in the Bavarian Alpine Foreland. Due to the small size of land snail shells and lack of specimens available for ESR analys...
Establishing patterns of frequency and magnitude of erosion events is key for understanding landscape evolution. For that purpose, luminescence dating is one of the most useful techniques as it can provide accurate chronology for sediment deposition. In this study, it has been applied to two stratigraphic profiles at the slopes of the Salar Grande,...
Extending the age range in luminescence dating is an important target in developing this technique. The limit is given by the saturation of the dose response curve, therefore, the efforts are focused on finding a stable luminescence signal that saturates at higher doses. Over the past years, alternatives like postIR-IRSL (Buylaert et al., 2012) or...
The recent introduction of post-IR IRSL measurement protocols has prompted a resurgence in luminescence applications using feldspar, some of which are affected by anomalous fading related signal loss. Many fading-corrected feldspar ages are reported in the literature, however few of those ages have been corrected using the model of Huntley (2006) [...
Eolian deposits such as loess-paleosol sequences are being used intensively for paleoenvironmental studies. In order to accurately interpret proxy data variability through time, reliable age models are essential. Age models are transferring stratigraphical thickness to geological time, and represent the basis of most studies investigating the timin...
The Shirasuka lowlands, located on the Enshu-nada coast of central Japan, record evidence for numerous extreme wave events. Here we test the applicability of using the luminescence signal from feldspars to date these young (< 1000 a) extreme wave event deposits. The signal used for dating is the IRSL signal (measured at 50?C) as part of a post-IR I...
The relevance of luminescence dating is re- flected by the steadily growing quantity of published data. At the same time, the amount of data available for analysis has increased due to technological and methodological advances. Routinely, luminescence data are analysed using a mixture of commercially available soft- ware, self-written tools and spe...
Understanding the past dynamics of large-scale atmospheric systems is crucial for our knowledge of the palaeoclimate conditions in Europe. Southeastern Europe currently lies at the border between Atlantic, Mediterranean, and continental climate zones. Past changes in the relative influence of associated atmospheric systems must have been recorded i...
Loess-paleosol sequences (LPS) represent an important terrestrial archive for the reconstruction of the paleoenvironmental evolution during the Last Glacial cycle in Europe. In the Rhine-Meuse area and the southwestern Germany, there are only few numerical ages determined with state-of-the-art luminescence methods, which limits the robustness of es...
Our knowledge about large earthquakes in stable continental regions comes from studies of faults that generated historical surface rupturing earthquakes or were identified by their recent imprint in the morphology. Here, we evaluate the co-seismic character and movement history of the Rauw fault in Belgium, which lacks geomorphological expression a...
Since the release of the R package 'Luminescence' in 2012 the functionality of the package has been greatly enhanced by implementing further functions for measurement data processing, statistical analysis and graphical output. Along with the accompanying increase in complexity of the package, working with the command-line interface of R can be tedi...
Whilst optically stimulated luminescence (OSL) is commonly more suitable for sediment dating because of faster signal resetting, thermoluminescence (TL) remains important for dating burnt material, e.g. in archaeological contexts, or for studying the luminescence properties of different materials. A lack of user-optimized analysis software for TL d...

The R package ’Luminescence’ is constantly evolving in both functionality and usability. One of its greatest potentials, barely yet exploited, is the capability of automated large-scale data processing (’data mining’), paving the way for exploratory analysis of OSL data. Here, we present an exemplary data analysis that makes use of the potential of...
Overlying a palustrine deposit of unknown age (complex FP), and protected from weathering and erosion inside a large cave/rock-shelter cavity, the sedimentary fill of Cueva Antón, a Middle Paleolithic site in SE Spain, corresponds in most part (sub-complexes AS2-to-AS5) to a ca.3 m-thick Upper Pleistocene terrace of the River Mula. Coupled with the...
The newly identified Paleolithic site Sima de Las Palomas de Teba hosts an almost seven-m-thick sediment profile investigated here to elucidate the rock shelter's chronostratigraphy and formation processes. At its base, the sediment sequence contains rich archeological deposits recording intensive occupation by Neanderthals. Luminescence provides a...
Numerical dating methods in Quaternary science are faced with the need to adequately visualise data consisting of estimates that have differing standard errors. Recent approaches either focus on the display of age frequency distributions that ignore the standard errors or on radial plots, that allow comparisons between estimates allowing for their...
The fluvial sediments at Cueva Antón, a Middle Palaeolithic rock shelter located in the valley of the River Mula (Southeast Spain), produced abundant lithic assemblages of Mousterian affinities. Radiocarbon dates are available for the upper part of the archaeological succession, while for the middle to lower parts chronometric data have been missin...
The first version of the R package ‘Luminescence’ was released and published in 2012. Since then, the package has been continuously improved by implementing further measurement protocols, adding age models, and extending functions. In geoscientific applications, luminescence dating requires a series of data processing procedures. A comprehensive an...
In luminescence dating an essential part concerns compelling presentation of equivalent doses. However, there is no ideal way to depict equivalent dose distributions with all their measures of uncertainty. Amongst others, most common approaches are the Radial Plot and kernel density estimate (KDE) graphs. Both plot types are supported by the R-pack...
Previous geochronological and archaeological studies on the rock shelter Jarama VI suggested a late survival of Neanderthals in central Iberia and the presence of lithic assemblages of Early Upper Paleolithic affinity. New data on granulometry, mineralogical composition, geochemical fingerprints and micromorphology of the sequence corroborate the p...
A practical guide for the R package „Luminescence‟ is provided. An introduction on data types in R is given first, followed by a guideline on how to import, analyse and visualise typical SAR-OSL measurement data.
