资源简介：
本数据集包含哀牢山构造带南段深变质岩带8件样品中角闪石和黑云母的Ar-Ar年代学数据，同时包含3件样品的磷灰石裂变径迹测年结果，这些数据结果投图表明哀牢山南段具有两阶段的剥露演化历史，即早期慢速隆升和晚期阶段的快速剥露，明显区别于点苍山杂岩体，表明二者属于不同的构造体制。
This dataset contains Ar-Ar geochronological data of amphibole and biotite from 8 samples collected from the deep metamorphic rock belt in the southern segment of the Ailao Shan Tectonic Belt, and additionally includes apatite fission-track dating results for 3 samples. Data plotting reveals that the southern segment of the Ailao Shan Tectonic Belt has a two-stage evolutionary history of exhumation, characterized by early slow uplift and late rapid exhumation. This pattern is distinctly different from that of the Diancangshan Complex, indicating that the two belong to distinct tectonic regimes.
