Data of the river sediment, surface sediment, and sediment cores of the Sunda Shelf

This dataset includes four files for the river sediment, surface sediment, and core sediment recovered from the Sunda Shelf. Four Excel files firstly show the variation of 14C dating results, grain size, clay mineral, and Sr-Nd isotopes versus core depth of three sediment cores from the Gulf of Thailand and the central Sunda Shelf; these files also present the clay mineral and Sr-Nd isotopic compositions of river sediment surrounding the Sunda Shelf and clay mineral compositions of surface sediment from the central Sunda Shelf.
