The average ages of the four tested samples, which range from 104 ± 15 to 118 ± 15 ka, are concordant with the age of eruption (112–115 ka) estimated based on geological evidence.
In conclusion, SAR–RTL dating of single quartz grains is reliable for dating the early stage of late Pleistocene volcanic events.
The potential of red thermoluminescence (RTL) emission from quartz, as a dosimeter for baked sediments and volcanic deposits, has received some attention over the past decade.
This paper presents a summary of the most important related results of our findings and outlines the configuration of photomultiplier and filter combinations which maximizes RTL detection for temperatures up to 500°C.
Op een datingsite ontmoette de 51-jarige man een paar dagen geleden een man met wie hij een date zou hebben.
Ze zouden elkaar ontmoeten op het parkeerterrein van het Willem II-stadion in Tilburg, het slachtoffer zou daar door zijn date opgehaald worden. Overvallen De Tilburger blijkt erin geluisd en is door 'zijn afspraakje' overvallen.
We have undertaken such an analysis using independently-dated silicic volcanic deposits from New Zealand, ranging in age from 300 ka through to 1.6 Ma.
We observed a complex RTL emission in most volcanic quartzes, which consists of a number of discrete high temperature (i.e, a.
We confirm the slow onset of saturation with dose, and the limited extent of sensitivity changes due to dosing and TL readout.
As such, there is much potential for exploiting the dosimeter in dating studies and we present the results from a modified single aliquot regenerative (SAR) procedures which indicate that there is a good agreement between RTL dating and other methods over time scales 10 a.
We performed the single aliquot regeneration–red thermal luminescence (SAR–RTL) dating on single quartz grains from Toya Caldera, northern Japan, which erupted during the late Pleistocene.
The use of an H7421-40 photomultiplier tube and a combination of R60 and IRC65L filters, which were developed for isothermal red thermoluminescence (IRTL), resulted in improved RTL signal detection, enabling weak RTL signals to be detected from a single quartz grain.
