Dating of glacial and glacier-related landforms and boulders in the Central Mountain Range of Taiwan with in-situ produced terrestrial cosmogenic nuclides (TCN)

The Central Mountain Range of Taiwan represents an exclusive location for palaeo-climate and palaeo-glaciation research in monsoonal East Asia as it provides high altitude terrestrial data in an oceanic environment. This study focuses on the dating of boulders and rock surfaces by means of paired (Be-10/ Al-26) in-situ produced cosmogenic nuclides in two mountain ranges - the Nenggao Shan and the Hsueh Shan - to estimate the time of previous glacier extents. The results will be presented in scientific journals available under the provided DOIs. Here we present the original AMS nuclide concentration measurement data of Be-10 and Al-26 and their ratios from 16 samples. The sample preparation including quartz separation as well as Be and Al isolation were carried out at the Purdue Rare Isotope Measurement Laboratory (PRIME Lab), Purdue University, West Lafayette, US., nuclide concentrations of Be-10 and Al-26 were determined by accelerator mass spectrometry (AMS). Field work and sampling were funded by the German Academic Exchange Service (DAAD), Grant 57137675. The sample analysis was funded by the German Research Foundation (DFG), Grant BO 659/28-1, project-no. 424056024.
