Journal ArticleDOI
Distinguishing quartz and feldspar in single grain luminescence measurements
TL;DR: In this paper, the authors proposed a method of distinguishing between quartz and feldspar based solely on their luminescence behavior, using the ratio of the OSL signal when measured with and without prior infrared stimulation.
Journal ArticleDOI
Developments in radiation, stimulation and observation facilities in luminescence measurements
TL;DR: The Riso TL/OSL reader as discussed by the authors has been extended to measure variable temperature radioluminescence (RL) during beta irradiation, which allows the measurement of TL, OSL and RL in the same software-controlled automatic sequence.
Journal ArticleDOI
Single-grain optical dating of Quaternary sediments: why aliquot size matters in luminescence dating
TL;DR: Single-grain Optically Stimulated Luminescence (OSL) as mentioned in this paper is a single-grain OSL method that can be used to determine whether a sample was bleached at deposition or not.
Journal ArticleDOI
DRAC: Dose Rate and Age Calculator for trapped charge dating
TL;DR: The Dose Rate and Age Calculator (DRAC) as discussed by the authors is an open access web-based program which enables rapid and accurate calculation of the environmental radiation dose rate (http://www.aber.ac.uk/alrl/drac ).

TL;DR: In this paper, morphologic and chronologic evidence indicates that fluvial landscapes in Harappan territory became remarkably stable during the late Holocene as aridification intensified in the region after approximately 5,000 BP.
