青藏高原东缘雅砻江逆冲带低温热年代学数据集

本数据集包含了雅砻江逆冲带的磷灰石和锆石的(U-Th)/He年龄数据，磷灰石的裂变径迹（AFT）年龄数据，该数据集后续会持续更新。第一部分数据是来自雅砻江逆冲带腹地分支断裂--玉农希断裂的磷灰石和锆石的 He以及磷灰石裂变径迹数据。第二部分数据是来自雅砻江逆冲断裂带的分支断裂锦屏山-木里断裂，包括磷灰石和锆石的 He年龄数据。数据结果较为集中，很好的约束了雅砻江逆冲带的演化，为探讨其在高原扩展过程中作用提供高质量的年代学依据。

This dataset contains apatite and zircon (U-Th)/He dating data as well as apatite fission track (AFT) age data from the Yalongjiang Thrust Belt, and will be continuously updated in the future. The first subset of data consists of apatite and zircon (U-Th)/He dating data, alongside apatite fission track (AFT) age data, collected from the Yunongxi Fault, a branch fault located in the hinterland of the Yalongjiang Thrust Belt. The second subset comprises apatite and zircon (U-Th)/He dating data obtained from the Jinpingshan-Muli Fault, another branch fault of the Yalongjiang Thrust Belt. The acquired dating results are relatively concentrated, which well constrain the evolutionary history of the Yalongjiang Thrust Belt, providing high-quality geochronological evidence for exploring its role during the expansion of the Tibetan Plateau.
