Abstract

Abstract:

Sedimentary records in the deserts are important archives for reconstructing the paleoclimate and paleoenvironmental change. In this study， three samples （LJB-MD-01， SCHGCMD-01， and M01） were collected from modern dunes in the Salawusu River Valley in the Mu Us Desert. Quartz single-grain optically stimulated luminescence （OSL） dating and K-feldspar single-grain post-infrared infrared stimulated luminescence dating （pIRIR） was used to determine the chronology of the sand dunes. The OSL and IRSL characteristics of the samples and the dose recovery test validate the dating protocols. The results suggest that：（1） the quartz OSL signal is very weak and is not suitable for OSL dating of young samples in the study area. （2） equivalent dose （D_e） determination of K-feldspar using pIRIR₁₇₀ protocol is reliable， with recycling ratio mostly ranging from 0.9-1.1， and recuperation less than 10%. （3） the anomalous fading rate （g-value） of IRSL₅₀ signals are 1.99±0.20 to 2.72±0.73% per decade and the g-value of pIRIR₁₇₀ are 0.02±0.03 to 0.69±0.31% per decade， suggesting that the low anomalous fading of pIRIR₁₇₀ can be neglected. （4） The K-feldspar pIRIR₁₇₀ ages for the three surface sand dunes， determined using the minimum age model， are 115±15 years， 150±20 years， and 25±5 years， respectively. These values align closely with the theoretical ages. The central age model estimates for the same dunes are 455±65 years， 420±55 years， and 30±25 years， respectively. These estimates are older than the theoretical ages. Thus， the current work suggests that K-feldspar single-grain pIRIR dating is applicable in the study area and provides a new approach for dating sediments， including the Mu Us Desert sediments， where OSL dating technology is not feasible due to the weak quartz signal.
