Visual core description of IODP Hole 386-M0083A@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-M0083A\"), 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）记录集（含手绘原稿与数字复制品）及岩性综合柱状图。本次VCD工作于2022年2月14日至2022年3月15日期间，在“地球号”（D/V Chikyu）科考船上开展的航次陆上阶段完成，操作对象为经分样后留存的未采样岩心归档半块，流程紧随线扫描成像之后。每份岩心段的岩性通过归档半块岩心段X射线计算机断层扫描（X-ray CT）图像旁的图形图案，在手绘VCD记录中予以呈现；此外，额外列项中还标注了表征沉积物特征的各类沉积属性与构造。随后，手绘VCD记录中的信息被录入钻井信息系统数据库（详见数据集"Description of lithologic section units of IODP Hole 386-M0083A"），可通过该数据库以半自动化方式调取数据，并借助Golden Software公司的Strater软件生成数字岩性柱状图与综合柱状图。[…]
