U-Pb dating of Triassic units from the Domeyko Range, northern Chile (I)

This dataset covers the U-Pb dating of detrital and igneous samples from Triassic units across the Domeyko Range in northern Chile. The geochronology provides time constraints for the maximum depositional ages and the crystallization ages of some of these units (Sierra de Varas, Cerro Guanaco, Quebrada del Salitre formations). Files comprise samples analyzed in the Laboratorio de Estudios Isotópicos (bre12305-sup-0004-supinfo4.xlsx) and Arizona LaserChron (bre12305-sup-0003-supinfo3) laboratories. Each sample includes information about the zircons considered and discarded in the calculation of dates.本数据集涵盖智利北部多梅伊科山脉（Domeyko Range）三叠系地层中碎屑岩与火成岩样品的U-Pb定年分析。其地质年代学数据可为部分地层——塞拉德拉瓦拉斯组（Sierra de Varas）、塞罗瓜纳科组（Cerro Guanaco）、奎拉达德尔萨利特尔组（Quebrada del Salitre）——的最大沉积年龄与结晶年龄提供时限约束。数据集文件包含两类分析样品：一类为同位素研究实验室（Laboratorio de Estudios Isotópicos）完成测试的样品，对应文件为bre12305-sup-0004-supinfo4.xlsx；另一类为亚利桑那激光年代学实验室（Arizona LaserChron）完成测试的样品，对应文件为bre12305-sup-0003-supinfo3。每份样品均包含定年计算过程中所选用与剔除的锆石相关信息。
