Clay mineral composition of sediments from International Ocean Discovery Program (IODP) Expedition 379 Hole U1532C, Amundsen Sea, West Antarctica (2019)

This data set presents contents of the clay minerals smectite, illite, chlorite and kaolinite analysed on the clay fraction (less than 2 micrometers) of Pleistocene-Holocene drift sediments recovered at Hole U1532A on the Amundsen Sea continental rise during IODP Exp379 with RV JOIDES Resolution in Jan-Mar 2019. The clay mineral contents are given in percentages both versus expedition number, site number, hole ID, core number, drill core type (H: advanced piston corer system, X: extended core barrel system; R: rotary core barrel system), section number (sect), section half (W: work; A: archive) and depth of the top and bottom of the sample within a section or core catcher (CC) in centimetres (cm) and versus depth below seafloor (CSF-A) in metres (m). The d-values (in Angstrom) and integral breadths (IB, delta 2theta) of the clay minerals smectite and illite as well as the ratios between the areas of the 5 Angstrom and 10 Angstrom peaks of illite are also given. The clay mineral data were generated and analysed by Dr Claus-Dieter Hillenbrand (British Antarctic Survey, Cambridge, United Kingdom) and Prof Werner Ehrmann (Institute of Geophysics and Geology, University of Leipzig, Germany). Users of this dataset should cite the dataset DOI and acknowledge both the data generators (C.-D. Hillenbrand and W. Ehrmann) and the International Ocean Discovery Program (IODP). The work was funded by NERC UK-IODP Moratorium Award NE/T010975/1.

本数据集收录了2019年1-3月期间，由“乔迪斯·决心号”（RV JOIDES Resolution）执行国际大洋发现计划（International Ocean Discovery Program, IODP）第379次航次时，在阿蒙森海陆隆U1532A钻孔采集的更新世-全新世漂积沉积物的黏土粒级（粒径小于2微米）组分中，蒙脱石、伊利石、绿泥石与高岭石的含量分析数据。
黏土矿物含量以百分比形式给出，同时配套标注了航次编号、站位编号、钻孔标识符（ID）、岩心编号、钻探取心类型（H：高级活塞取心系统（advanced piston corer system）；X：加长取心筒系统（extended core barrel system）；R：旋转取心筒系统（rotary core barrel system））、节段编号（sect）、节段半段（W：工作半段；A：归档半段）、样品在节段内或岩心爪（core catcher, CC）中的顶底深度（单位：厘米，cm），以及相对于海底以下深度（CSF-A，单位：米，m）。
此外，数据集还提供了蒙脱石与伊利石的晶面间距d值（单位：埃，Å）、积分宽度（integral breadth, IB，Δ2θ），以及伊利石5埃与10埃特征衍射峰的峰面积比值。
本数据集的黏土矿物数据由英国剑桥英国南极调查局的克劳斯-迪特尔·希伦布兰德博士（Claus-Dieter Hillenbrand）与德国莱比锡大学地球物理学与地质学研究所的维尔纳·埃尔曼教授（Werner Ehrmann）完成生成与分析。
使用本数据集的用户需引用该数据集的数字对象唯一标识符（Digital Object Identifier, DOI），并对数据生成者（C.-D. 希伦布兰德与W. 埃尔曼）以及国际大洋发现计划（IODP）致谢。
本项工作由英国自然环境研究委员会（Natural Environment Research Council, NERC）旗下的UK-IODP延期资助项目NE/T010975/1资助。
