Complete whole-rock geochemical dataset (major and trace elements) from Archean and Ediacaran rocks of the Northwest Chami Thrust Belt, NW Mauritania

This dataset contains the complete whole-rock geochemical data (major and trace elements) from Archean and Ediacaran rocks of the Northwest Chami Thrust Belt (NW Mauritania). These data underpin the results presented in the associated manuscript entitled "SHRIMP U–Pb zircon protolith ages in northwestern Mauritania reveal Archean TTGs and Ediacaran subduction-related granitoids" and are provided to ensure transparency and facilitate data reuse.本数据集包含采自毛里塔尼亚西北部查米逆冲带的太古宙与埃迪卡拉纪岩石的完整全岩地球化学数据（主量元素与微量元素）。上述数据为相关学术论文的研究结果提供了支撑，该论文题为《毛里塔尼亚西北部SHRIMP锆石原岩U-Pb年龄揭示太古宙TTG与埃迪卡拉纪俯冲相关花岗岩类》。本数据集公开发布旨在保障研究透明度并促进数据复用。
