Abstract:
This data set presents chemical compositions and Sr isotope ratios of bulk sediments and fish teeth taken from the piston and pilot cores, which were collected from the deep-sea basin around Minamitorishima Island, the western North Pacific. The cores were obtained during Cruises KR13-02, MR13-E02, MR14-E02, and MR15-E01 by R/Vs Kairei and Mirai. All the samples are categorized into pelagic clay or silty clay with variable amounts of biogenic Ca-phosphate and zeolite. Cores KR13-02 PC04, PC05, and PC06 contain one or two layers with >2000 ppm of total rare-earth elements and yttrium (REY) concentration, called “1st REY peak” and “2nd REY peak”. In addition, the pelagic clay samples in this area can be classified into five groups (Unit I to V), based on the chemical compositional characteristics (chemostratigraphy; Tanaka et al., 2020 Ore Geology Reviews). The sediment samples in this data set cover all the chemostratigraphic units (Unit I to V), the 1st and 2nd REY peaks.
