Visual core description of IODP Hole 386-M0085A@en

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-M0085A\"), from where it could be accessed semi-automated to produce digital lithologic columns and composite plots using Strater (Golden Software). […]本数据集包含国际大洋发现计划（International Ocean Discovery Program, IODP）386次科考航次（日本海沟古地震研究）指定钻孔的岩心目视描述（Visual Core Description，VCD）表（含手绘原稿与数字化副本）以及岩性综合柱状图。本次386航次的陆上作业阶段于2022年2月14日至2022年3月15日在“地球号”（D/V Chikyu）钻探船上开展，VCD工作即在该阶段于劈开岩心的未采样保存半体上开展，且于岩心线扫描成像完成后立即进行。手绘VCD表中，各岩心段的岩性通过对应保存半芯X射线计算机断层扫描（X-ray CT）图像旁的图形图案进行表征。此外，额外列中还标注了多种表征沉积物特征的标识。随后，手绘VCD表中的信息被录入钻探信息系统（Drilling Information System）数据库（详见数据集《IODP 386-M0085A孔岩性段单元描述》），工作人员可通过该数据库半自动化调取信息，使用Strater（Golden Software公司开发）生成数字化岩性柱状图与综合柱状图。[…]
