复杂山区泥石流、堰塞湖沉积物测年数据（2019-2021）

2019-2021年的复杂山区泥石流、堰塞湖沉积物测年数据。数据采集地点为青藏高原东缘、南缘等区域泥石流易发的复杂山区。主要在中国科学院青海盐湖研究所盐湖化学分析测试中心、中国科学院成都山地所分析测试中心等完成实验分析。使用的仪器包括Risø TL/OSL–DA–20全自动释光仪等。建立了典型复杂山区泥石流沉积物年代数据集，定量研究了复杂山区泥石流沉积物的形成年代，确定了复杂山区的古泥石流灾害活动历史。

This dataset contains chronological dating data of debris flow and barrier lake sediments in complex mountainous areas from 2019 to 2021. The sampling sites are located in complex mountainous regions prone to debris flows, such as the eastern and southern margins of the Qinghai-Tibet Plateau. Most experimental analyses were carried out at the Salt Lake Chemical Analysis and Testing Center of the Qinghai Institute of Salt Lakes, Chinese Academy of Sciences, and the Analytical Testing Center of the Chengdu Institute of Mountain Hazards and Environment, Chinese Academy of Sciences, alongside other relevant institutions. The equipment used includes the Risø TL/OSL–DA–20 fully automated optically stimulated luminescence (OSL) dating system and other related instruments. A chronological dataset of debris flow sediments in typical complex mountainous areas was established, which enabled the quantitative investigation of the formation ages of debris flow sediments in complex mountainous areas and the clarification of the historical activity records of paleo-debris flow disasters in these regions.
