The single-aliquot regenerative-dose (SAR) protocol applied to coarse-grain feldspar

The single-aliquot regenerative-dose (SAR) protocol applied to coarse-grain feldspar The application of the single-aliquot regenerative-dose (SAR) protocol to equivalent dose determination in coarse-grain feldspar is investigated.

It is shown that the method is robust and yields results similar to those obtained with a single-aliquot additive-dose (SAAD) procedure.

Abstract

The application of the single-aliquot regenerative-dose (SAR) protocol to equivalent dose determination in coarse-grain feldspar is investigated. An outline of the protocol is presented, and basic tests of its performance are discussed. It is shown that the method is robust and yields results similar to those obtained with a single-aliquot additive-dose (SAAD) procedure. The use of the SAR procedure for fading tests is also discussed. We conclude that the SAR protocol for coarse-grain feldspar yields several advantages over previously used multiple-aliquot and single-aliquot methods. The method is fast and precise, the equivalent dose is obtained by interpolation, and the method corrects for sensitivity changes. The luminescence age obtained by SAR and additive-dose dating of the coarse-grain feldspar separates used in this study do, however, underestimate the independently estimated geological age of the samples.
