Characterisation and OSL dating of modern fluvial sediments in the lower Vistula River: testing the zeroing assumption

Abstract

Abstract. In this study modern sediments of the lower Vistula River were investigated to determine the relationship between the structure and texture (grain size, rounding and frosting) of the deposits and the possibility of their zeroing. The samples of modern fluvial deposits were collected from the lower Vistula River at two sites in Toruń and Ciechocinek. Sand bars newly emerged from the river were selected for testing. The coarse quartz grains were separated for OSL measurements. The single-aliquot regenerative (SAR) technique was applied for measuring equivalent doses from multigrain aliquots. The obtained dose estimates were found to be very low, proving the reliability of the OSL zeroing assumption. The dose rates were estimated by gamma-ray spectrometry, demonstrating homogeneity of the radiation field. Analysis did not show significant relationships between the examined sediments' capacity to zeroing and their structural and textural characteristics, or the sampling site. The obtained OSL ages of the studied sediments date back hundreds of years and are probably overestimated. The results related to fossil sediments of bars of the age of thousands of years confirm their suitability for the OSL dating method.

Luminescence as a Sediment Tracer and Provenance Tool

“…Most research into bleaching has focused on river systems, but bleaching varies greatly by geomorphic environment (Alexanderson, ; Jaiswal et al, ; Przegiętka et al, ; Schielein & Lomax, ; Weckwerth et al, ). For a given luminescence signal (OSL or IRSL), aeolian sediments often show lower residual doses (remnant luminescence) than other types of sediment (Buylaert et al, ; Singarayer et al, ).…”

Braided–meandering system evolution in the rock record: Implications for climate control on the Middle–Upper Jurassic in the southern Junggar Basin, north‐west China

“…However, studies of the well-exposed three-dimensional fluvial outcrops fill this gap, because they necessarily focus on what is actually preserved. A series of researches on the fluvial systems have made a major breakthrough, that includes (a) fluvial patterns and classification (Assine, Silva, Latrubesse, Chen, & Stevaux, 2009;Rosgen, 1994;Schumm, 1977;Schumm & Khan, 1971;Wu et al, 2016); (b) a survey of modern fluvial systems (Langford, 2010;Przegiętka, Molewski, Juśkiewicz, Palczewski, & Chabowski, 2016;Sambrook Smith et al, 2010;Weissmann et al, 2015); (c) the facies and modelling (Bridge & Lunt, 2006;Cant & Walker, 1978;Davidson, Leleu, & North, 2011;Lunt & Bridge, 2004;Miall, 1977b); (d) the sequence stratigraphy of fluvial systems (Beer, 2005;Catuneanu & Eriksson, 2006;Colombera, Mountney, & McCaffrey, 2015;Miall, 2002;Miall, 2006); (e) the architecture element (Allen, 1983;Miall, 1985;Miall, 1992;Miall, 1996a;Miall, 2002;Miall, 2006;Miall, 2014a); (f) the simulation of sedimentation (Jang, Shimizu, & Lee, 2015;Kettner, Restrepo, & Syvitski, 2010).
