Computerised glow curve deconvolution
|Abstract:||<smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="metricconverter"> Computerised Glow Curve Deconvolution (CGCD) of glow curves of (N, N+10 and N+15 Gy) sedimentary quartz has been studied. Equivalent dose (ED) of the sample has been evaluated using the well-known additive dose method by using the individual glow peaks obtained by deconvolution. For unheated sediments, ED can be evaluated either using 312°C peak or 276°C peak. The high temperature peaks, located by us around 420, 458, 488 and 540°C normally not considered for dating may also be used in case of heated sediments/potteries/bricks. Unlike the random values of trap-depth reported in some recent paper, our CGCD results clearly show a linear relation between <i>E</i>~<i>kT</i><sub>m</sub> plot, yielding a physically realistic Urbach’s co-efficient i.e. 27 for quartz. </smarttagtype>|
