Northern Hemisphere summer insolation and ice volume driven variations in hydrological environment in southwest China

This dataset from a stalagmite record from Chongqing, Southwest China, provides a high-resolution trace element record from the Last Glacial-Interglacial (116.09 to 4.07 ka BP) up to the sub-centennial scale. Line scans of Element/Calcium ratios of the speleothem were measured by laser ablation ICPMS. Chronology is based on 58 U-Th ages.本数据集源自中国西南重庆的石笋记录，提供了覆盖末次冰期-间冰期时段（116.09~4.07 ka BP）、分辨率可达亚百年尺度的高分辨率微量元素序列。该石笋的元素/钙比值线扫描数据通过激光剥蚀电感耦合等离子体质谱（laser ablation ICPMS）测定。其年代框架基于58组铀钍（U-Th）测年结果。
