Rb–Sr and Sm–Nd isotopic data and mixing models for basalt and impact glass fragments from Chang’e-5 lunar soil Honggang Zhu (24238689) Planetary science (excl. solar system and planetary geology) Chang’e-5 samples <p dir="ltr">This dataset accompanies the manuscript “Provenance of exotic KREEP-rich materials in Chang’E-5 lunar soil constrained by Sr-Nd isotopes”.</p><p dir="ltr">The study investigates the origin and mixing relationships of KREEP-rich materials in lunar soil returned by the Chang’E-5 mission. The analyzed samples comprise seven basalt fragments and five impact glass fragments selected from lunar soil sample CE5C0400YJFM00406.</p><p dir="ltr">The dataset contains Rb, Sr, Sm, and Nd concentrations and Sr–Nd isotopic compositions of the 12 fragments, corresponding to Table 1 of the manuscript, together with two-endmember mixing model results corresponding to Supplementary Table S1. These data support the evaluation of mixing between local Chang’E-5 basalt and a KREEP-rich component.</p><p dir="ltr">Sample identifiers correspond to those used in the manuscript. Analytical uncertainties, units, and definitions of calculated parameters are provided in the accompanying tables and notes.</p> 2026-09-27T08:17:23Z Dataset Dataset 10.6084/m9.figshare.34004502.v1 https://figshare.com/articles/dataset/Rb_Sr_and_Sm_Nd_isotopic_data_and_mixing_models_for_basalt_and_impact_glass_fragments_from_Chang_e-5_lunar_soil/34004502 CC BY 4.0
