2026-05-11 Changning-Menglian Orogenic Belt: Evidence from Grain-size Analysis, Detrital Composition, and Zircon U-Pb Geochronology of the Metasandstones doi:10.57760/sciencedb.36010 en This dataset contains detrital zircon U-Pb dating test data of sedimentary rocks in the southern section of the Changning Menglian tectonic belt. The data was tested using LA-ICP-MS method, which includes 180 sets of effective zircon age data, covering key parameters such as zircon U-Pb age, U/Th ratio, and harmonic degree. The data aims to provide basic geochronological support for the evolution of the Tethys tectonic domain, source analysis of the southern group, and paleogeographic reconstruction. It can be used for detrital zircon age spectrum analysis, source tracing, and regional stratigraphic correlation research.  Changning-Menglian Suture Belt; Nanduan Formation; Zircon U-Pb Geochronology Chen Hongsheng EMBARGO https://creativecommons.org/licenses/by/4.0/ dataset Science Data Bank
