A high-resolution analysis of the Zmajevac loess-palaeosol sequence in East Croatia (Baranja) was performed with the purpose to get new insights into the palaeoenvironmental history during the last three glacial-interglacial cycles. The post-IR infrared stimulated luminescence signal of feldspar, stimulated at 290°C (thereafter pIRIR290) was used t...
Article
Previous studies observed that the single aliquot regenerative-dose (SAR) protocol is problematic for the quartz violet stimulated luminescence (VSL) signal. We therefore evaluate the reliability of multiple aliquot approaches, i.e. single aliquot regeneration and added dose (SARA) and sensitivity-corrected multiple aliquot regenerative-dose (SC-MA...
Article
The Gulf of Mexico coastal plain contains one of the largest dune systems in Mexico. These dunes and particularly their paleosols contain valuable paleoenvironmental information, however this aspect has been poorly studied. Here, we present the preliminary results obtained from buried paleosols of coastal dune ridges in Veracruz with the aim to rec...

Seismic activity in northern Germany is rare, but recent earthquakes were recorded e.g. east of Hamburg and in the Halle/Leipzig area. Many of these earthquakes occur at major Cretaceous reverse faults. A possible trigger mechanism is the release of lithospheric stress changes due to post-glacial isostatic adjustment, which was initiated in the Lat...
Article
In response to the comment of Madsen and Liu (2018), we explain why our quartz optically stimulated luminescence (OSL) ages showing the early MIS 3 lake highstand are robust. We also demonstrate that the difference in the age estimates between ours (Long et al., 2018) and other studies should be attributed to contrasting equivalent dose (De) values...

Article
Organic-poor, permeable quartz sands are often present at land-sea transition zones in coastal regions. Yet, the biogeochemical cycles of carbon, sulfur, and iron are not well studied here. The aim of this work was, therefore, to improve our understanding regarding the chemical processes in these prominent coastal sediments. A 10 m core was collect...
Article
Coastal boulder deposits and chevrons are two features whose origin have triggered controversial discussions. Boulders are often used as indicators of past tsunamis and storms, with the former interpretation in many cases preferred due to the clast size. Chevrons, defined as large parabolic sand bodies, were previously attributed to (mega‐)tsunami,...
