Clay mineral assemblage, major element composition and carbonate content of core GIK18383-3 in the southern South China Sea during SONNE cruise SO140A@en

This data set includes clay mineral assemblage, major element composition and carbonate content of Core SO18383-3 retrieved in the southern South China Sea during the cruise SO140 on R/V SONNE. The Core SO18383-3 is located at 7º38.54'N, 109º29.15'E, and is 710.6 m water depth and 9.44 m long. The clay mineral assemblage (237 samples, 4 cm resolution) was analyzed by X-ray diffraction (XRD) using a PANalytical X'Pert PRO diffractometer on oriented mounts of non-calcareous, clay-sized particles. The major element composition (166 samples, 4-8 cm resolutions) was analyzed by X-ray fluorescence (XRF) using a PANalytical Axios MAX Spectrometer on bulk sediments. The carbonate content was analyzed by the gasometric method on bulk sediments.
