Stable isotope and U/Th speleothem measurements from Vietnam, 200,000–334 years BP

The data includes carbon and oxygen stable isotopes together with top and bottom U-Th ages of stalagmites collected in Northwest, Central and Southern Vietnam. The purpose of this work was to identify suitable specimens that can be used for palaeoclimatic reconstructions. The stalagmites collected were found broken in-situ, and the exact location of the caves is not given here for cave protection purposes. The stalagmites were collected in February and March 2023, and geochemical analyses performed between April and December 2023.
