Isochron dating of sediments using luminescence of K-feldspar grains
[1] A new method for dating well-bleached sediments is presented, with results for thirteen samples from China. The method uses an isochron constructed from the measurement of natural radiation doses received by potassium-feldspar grains in a range of grain sizes using the infrared stimulated luminescence (IRSL) signal. The age of deposition of the sediment is calculated from this isochron and ...
متن کاملReply to comment by Huntley on "Isochron dating of sediments using luminescence of K-feldspar grains"
In our isochron studies using grains of different sizes, we observed that the IRSL ages obtained from K‐feldspar without correction for fading show an increase with increasing grain size [Li et al., 2007, 2008]. Huntley [2011a] argued that this result was caused by different fading rates for grains of different sizes or by different source materials for different sizes of grains. We replied to ...
متن کاملA reply to the comments by Thomsen et al. on "Luminescence dating of K-feldspar from sediments: a protocol without anomalous fading correction"
We are pleased that Thomsen et al. (2012) has tested our newly proposed multi-elevated-temperature post-IR IRSL (MET-pIRIR) procedure (Li and Li, 2011) using their own samples, which provides an independent test on the validity of this procedure. In their study, Thomsen et al. (2012) found that the METpIRIR procedure gave consistent results with the two-step post-IR IRSL (TS-pIRIR) procedure or...
متن کاملGeomorphological correlation of the tectonically displaced Tejo River terraces (Gavião–Chamusca area, central Portugal) supported by luminescence dating
A suite of fluvial terraces (T1–T6, from top to bottom of the staircase) occur along a 70 km stretch of the Tejo River in central Portugal, between the small towns of Gavião and Chamusca. Terrace correlation was based upon the following: (a) aerial photograph analysis, geomorphological mapping and field topographic survey; (b) sedimentology of the terrace deposits, namely the maximum particle s...
متن کاملTesting feldspar luminescence dating of young archaeological heated materials using potshards from Pella (Tell Tabqat Fahl) in the Jordan valley
Recent developments in the use of more stable feldspar signals in the luminescence dating of sediments offer the possibility of obtaining accurate feldspar luminescence ages for ceramic artefacts; this is especially interesting in locations which do not provide suitable quartz extracts. Here we examine the application of the stable infrared stimulated luminescence signal measured at elevated te...
