Brief Introduction

Luminescence dating technique, especially the quartz OSL dating approach, provides a powerful tool for chronology construction during the late Pleistocene and the Holocene. It can date aeolian, fluvial, lacustrine sediments and some others, of which aeolian material is the most appropriate.

We focus on methodological improvements and application of luminescence dating in Chinese loess since the establishment of the luminescence dating laboratory in 1985. We have applied different luminescence dating techniques into classical sections (e.g. Lantian, Luochuan, Weinan, Jingyuan, Gulang) on the Chinese Loess Plateau.

There are 3 sets of automated Daybreak 2200 TL/OSL and 1 set of automated Riso TL/OSL DA-20 measurement systems in this laboratory. In the past several years, we have provided many luminescence ages for many scientists around the world.

 

Research Interests

Ø Luminescence dating method research by using quartz and feldspar grains

Ø Luminescence dating of late Quaternary deposits, especially type of aeolian formed sediments (e.g. loess, sand dunes)
