Major and trace element geochemistry of Japan Trench sediments (IODP 343-C0019E and DSDP 56-436)

Abstract: This dataset contains major and trace element geochemistry from IODP 343-C0019E (J-FAST) and DSDP 56-436. IODP 343-C0019E drilled through the toe of the accretionary prism in the Japan trench and contains tectonically disrupted sediments that are difficult to date. DSDP 56-436 is located nearby on the incoming plate and contains a reference section for the tectonically disrupted sediments in hole C0019E. Correlation of the samples based upon major and trace element chemistry allowed dating of the sediments in hole C0019E and recognition of additional faults.

摘要：本数据集包含来自国际大洋发现计划（IODP）343-C0019E（J-FAST）与深海钻探计划（DSDP）56-436的常量与微量元素地球化学数据。IODP 343-C0019E钻孔穿透了日本海沟增生楔的趾部，所获岩心含有难以定年的构造扰动沉积物。DSDP 56-436站位地处邻近的即将俯冲入海沟的板块之上，为C0019E钻孔中的构造扰动沉积物提供了参考剖面。基于常量与微量元素地球化学特征对样品进行对比分析，得以实现C0019E钻孔沉积物的定年，并识别出额外的断层。
