Visual core description of IODP Hole 386-M0084C

Collection of visual core description (VCD) sheets (hand drawn originals and digital representations) and lithologic composite plots from the above given hole of International Ocean Discovery Program (IODP) Expedition 386 (Japan Trench Paleoseismology). VCD was performed on unsampled archive halves of split cores, directly after linescan imaging, during the onshore phase of expedition 386, which took place between 2022-02-14 – 2022-03-15 onboard D/V Chikyu. The lithology of each core section is represented on the hand drawn VCDs by graphic patterns next to the X-ray CT image of the archive-half core section. Further, a wide variety of features that characterize the sediment are indicated in additional columns. The information from the hand-drawn VCD sheets was then transferred into the Drilling Information System database (s. also datasets "Description of lithologic section units of IODP Hole 386-M0084C"), from where it could be accessed semi-automated to produce digital lithologic columns and composite plots using Strater (Golden Software).For further methodological information see methods chapter in Strasser, M. et al., 2023 https://doi.org/10.14379/iodp.proc.386.102.2023

国际大洋发现计划（IODP）386航次（日本海沟古地震学）中上述钻孔的视觉岩心描述（VCD）表（手绘原稿及数字化版本）与岩性复合图数据集。VCD工作于386航次的陆上阶段（2022年2月14日至3月15日，在‘地球号’钻探船（D/V Chikyu）上开展）中，在线扫描成像后立即对未取样的岩心劈开面存档半块进行。手绘VCD表中，每个岩心段的岩性通过存档半块岩心段X射线计算机断层扫描（CT）图像旁的图形模式来表示；此外，表征沉积物的各类特征在附加列中予以标注。手绘VCD表中的信息随后被转入钻井信息系统数据库（另见数据集‘IODP 386-M0084C钻孔岩性段单元描述（Description of lithologic section units of IODP Hole 386-M0084C）’）；从此数据库可通过半自动化方式调取信息，利用Strater软件（Golden Software公司）生成数字化岩性柱与复合图。更多方法学信息请参见Strasser等人2023年发表的方法章节（https://doi.org/10.14379/iodp.proc.386.102.2023）。
