Distinguishing quartz and feldspar in single grain luminescence measurements
TLDR
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.About:

A review of quartz optically stimulated luminescence characteristics and their relevance in single-aliquot regeneration dating protocols
Ann G. Wintle,Andrew S. Murray +1 more
TL;DR: Different single-aliquot regenerative-dose (SAR) protocols have been applied for some years to quartz grains for determining the equivalent dose, in both dating and retrospective dosimetry studies as mentioned in this paper.

TL;DR: The results of new excavations conducted at Madjedbebe, a rock shelter in northern Australia, set a new minimum age of around 65,000 years ago for the arrival of humans in Australia, the dispersal of modern humans out of Africa, and the subsequent interactions ofmodern humans with Neanderthals and Denisovans.

Statistical aspects of equivalent dose and error calculation and display in OSL dating: An overview and some recommendations
TL;DR: In this article, the statistical estimation of uncertainties and variation for comparing and interpreting age estimates, with specific reference to the estimation of equivalent dose (De) values in the optically stimulated luminescence (OSL) dating of sediments.
Journal ArticleDOI
Optical dating of Holocene sediments from a variety of geomorphic settings using single grains of quartz
TL;DR: In this article, an improved method for the optical dating of Holocene sediments from a variety of geomorphic settings was presented, where the authors measured the equivalent dose (De) in individual grains of quartz, using green laser light for optical stimulation, and simulated the De distributions for multiple-grain synthetic aliquots using the singlegrain data.
Journal ArticleDOI
Ancient watercourses and biogeography of the Sahara explain the peopling of the desert
TL;DR: The dating of lacustrine sediments show that the “green Sahara” also existed during the last interglacial and provided green corridors that could have formed dispersal routes at a likely time for the migration of modern humans out of Africa.

Luminescence dating of quartz using an improved single aliquot regenerative-dose protocol
Andrew S. Murray,Ann G. Wintle +1 more
TL;DR: In this paper, the authors examined the interpretation of the sensitivity corrected growth curve as a function of dose, and the effect of changing measurement conditions (e.g., preheat temperature, size of test dose, stimulation temperature) on the estimation of De.

TL;DR: Two abstract representations engraved on pieces of red ochre recovered from the Middle Stone Age layers at Blombos Cave in South Africa support the emergence of modern human behavior in Africa at least 35,000 years before the start of the Upper Paleolithic.

Advances in luminescence instrument systems
TL;DR: In this article, the authors report on recent advances in the development of luminescence measurement systems and techniques at Riso, including optical stimulation units based on new-generation powerful blue light (470-nm) emitting diodes providing up to 28 mW/cm2 for OSL measurements.

The anomalous fading of infrared-stimulated luminescence from feldspars
TL;DR: In this paper, anomalous fading of infrared-stimulated luminescence (IRSL) was measured for a suite of identified feldspars stored for periods of up to 15 months at temperatures of ∼10°C and 100°C.
