青藏高原东部马尔康黄土年代与环境指标数据

本数据为青藏高原东部马尔康黄土的石英光释光年代、碳十四年代、磁化率和粒度等数据。石英光释光测年、粒度、磁化率等分析在兰州大学西部环境教育部重点实验室完成；AMS碳十四样品测试在北京大学完成。该数据提供了青藏高原东部马尔康地区黄土沉积三阶段（MIS3）以来的可靠年代序列，和粉尘沉积历史以及古环境变化特征，对深入研究青藏高原末次冰期以来的环境变化，粉尘活动历史及其与周边大气环流之间的联系具有重要的作用。

This dataset contains quartz optically stimulated luminescence (OSL) ages, radiocarbon ages, magnetic susceptibility, and grain size data of loess deposits in Barkam, eastern Tibetan Plateau. Analyses including quartz OSL dating, grain size measurement, and magnetic susceptibility testing were conducted at the Key Laboratory of Western China's Environmental Systems (Ministry of Education), Lanzhou University, while AMS radiocarbon dating of samples was completed at Peking University. This dataset provides a reliable chronological sequence of loess deposits in the Barkam region, eastern Tibetan Plateau since Marine Isotope Stage 3 (MIS3), alongside records of dust deposition history and paleoenvironmental change characteristics. It is of great significance for in-depth studies of environmental changes on the Tibetan Plateau since the Last Glacial Period, dust activity history, and their linkages with surrounding atmospheric circulations.
