Testing a single-aliquot protocol for recuperated OSL dating

Radiation Measurements, 2007
Abstract A single-aliquot dating procedure for measuring the equivalent dose in fine-grained quartz extracted from Chinese loess has been developed and tested. The optically stimulated luminescence (OSL) signal used for construction of the dose–response curve is termed the recuperated OSL (ReOSL) signal; it is the difference between the thermally ...

OSL Dating in Archaeology

2006
The OSL (optically stimulated luminescence) dating method exploits dosimetric properties of grains of minerals naturally occurring in sediments and man-made materials.

OSL properties of NaCl relative to dating and dosimetry

Radiation Measurements, 2000
Abstract The luminescence properties of NaCl are discussed. Attention is focussed predominantly upon the optically stimulated luminescence (OSL) signal (UV emission) of NaCl (420–560 nm stimulation). The results from experiments relevant to geological dating applications, such as signal resetting, dose response and thermal stability, are described ...

Thermal pre-treatment in the OSL dating of quartz: is it necessary?

Radiation Protection Dosimetry, 2006
Thermal treatment before optically stimulated luminescence (OSL) measurement is an important step in all widely accepted OSL dating procedures used with quartz. This is a major constraint on the design of a portable luminescence instrument for estimating ages in the field.

Development of a spatially resolved dating technique using HR-OSL

Radiation Measurements, 2006
Abstract Analogous to the OSL dating of sediments, it should be possible to determine the point in time at which the bleached surface of a stony object became ultimately shielded from light. This would enable us to date various archaeological and geological events, such as the construction and destruction of stone buildings, the burial of stone ...

OSL dating of tsunami deposits from Phra Thong Island, Thailand

Quaternary Geochronology, 2012
Abstract To evaluate the potential of optical dating (OSL) in establishing a proper tsunami chronology for Phra Thong Island (SW Thailand), the method was applied to a suite of tsunamigenic and littoral sandy deposits, for which independent age control was available.

A theoretical model for a new dating protocol for quartz based on thermally transferred OSL (TT-OSL)

Radiation Measurements, 2008
Abstract Recently a new dating procedure has been suggested, which is based on the thermally transferred optically stimulated luminescence (TT-OSL) signal that is measured after irradiated quartz is optically bleached and then preheated. Experimentally the TT-OSL signal was measured after a high temperature preheat ( 260 ∘ C for 10 s ...

New quartz technique for OSL dating of limestones

2010
The equivalent dose De determination of limestone-made ancient constructions by thermoluminescence (TL) prevents accurate measurements and requires plateau test of bleached curves. Optical stimulated luminescence (OSL) of quartz and feldspar minerals for surface dating is routinely applied for De but not for limestones.
