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 ...

پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...
15 صفحه اولA Simple Method to Separate Quartz and Feldspar and Its Application to Tl/osl Methods
In the dating of sediments by luminescence methods, to obtain a sample the purest possible as to its mineralogy determines the rest of the analytical procedures. The isolation of the sample minerals is a critical stage due to the impossibility of quantifying the relative contributions to the dose from the different minerals. In this paper we propose a non chemical method to isolate quartz from ...
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...
