Latest Pleistocene to Holocene loess in the central Great Plains: Optically stimulated luminescence dating and multi-proxy analysis of the enders loess section (Nebraska, USA)

Guide for interpreting and reporting luminescence dating results

“…Supplemental materials may also include information about the measurement protocol, such as stimulation and detection wavelengths, preheat temperatures, and other parameters used for D E measurement. Other information in supplemental data sections could also include sample response to replication and data quality tests (e.g., dose-recovery and preheat-plateau tests), the influence of variable water content and dose-rate disequilibrium, sampling site profiles, and photographs (e.g., Feathers et al, 2020;Pazzaglia et al, 2021;Tecsa et al, 2020). Ideally, well-documented and researched papers will also include signal decay curves (for optically stimulated luminescence [OSL]) or glowcurves (for thermoluminescence [TL]), representative dose response curves, information on the luminescence signal properties (characteristic dose of saturation, proportion of fast-decay component, etc.…”

Initial quartz OSL and dust mass accumulation rate investigation of the Kisiljevo loess sequence in north-eastern Serbia

“…The observed age underestimation varies from 13% for sample ZAT 1/0.41 to 42% for the uppermost sample (ZAT 2/0.395). While the 13% underestimation at about 30 ka is to be J o u r n a l P r e -p r o o f 13 expected based on our previous observations on other sites (Constantin et al, 2015;Timar-Gabor et al, 2017) we currently have no explanation for the significant underestimation in the case of the age obtained using fine grains for sample ZAT 2/0.395, as usually a good agreement is reported between fine and coarse ages for that particular age range (Constantin et al, 2019;Tecsa et al, 2020). In the study of Timar-Gabor et al (2015), similar age underestimation of the 4-11µm quartz was observed for the Orlovat LPS in northern Serbia for ages older than ~30 ka.…”

Hydrology of a Semiarid Loess‐Paleosol Sequence, and Implications for Buried Soil Connection to the Modern Climate, Plant‐Available Moisture, and Loess Tableland Persistence

“…This variation may be a result of varying sampling depth within the Brady Soil's thick Akb horizon. Closely spaced particle size analyses through the Brady Soil have revealed abrupt variations in PSD with depth (Miao et al., 2007; Tecsa et al., 2020), which could be reflected by similar variation in hydraulic properties. The same could be true to some extent of the upper paleosols (e.g., variation of n among Paleosol 1 replicates).…”

“…The particle size distribution was calculated using the Mie optical model, with the refractive index and adsorption set to 1.55 and 0.1, respectively. We did not pretreat the samples to remove OC or carbonates because previous studies showed that these pretreatments did not increase the percentages of fine grain‐size fractions in similar soils (Mason et al., 2007; Tecsa et al., 2020).…”
