This datasets contain the XRF-scanning records of major terrigenous elements (Ti and Fe) and their ratios to the calcium content in the bulk sediment, obtained from six cores from the Western Equatorial Pacific. Records of the six cores are listed in separate datasets as: KX21-2 (01°25.0'S, 157°58.9'E, 1897 m water depth), KX22-4 (00°01.7'S, 159°14.7'E, 2362 m water depth), KX12-1 (01°48.8'S, 143°40.1'E, 1568 m water depth), KX13-1 (01°14.4'S, 140°00.9'E, 2987 m water depth), KX15-2 (04°07.3'S, 145°36.2'E, 2063 m water depth), KX10-1 (03°20.3'N, 131°50.5'E, 2216 m water depth).
