Description of lithologic section units of IODP Hole 386-M0091A@en

Description of lithologic section units from the above given hole of International Ocean Discovery Program (IODP) Expedition 386 (Japan Trench Paleoseismology). The content of this dataset is based on the visual core descriptions (VCD) done by sedimentologists during the onshore phase of expedition 386 (2022-02-14 – 2022-03-15 onboard D/V Chikyu). For digitalization of the information, content of the hand-drawn VCD sheets was transferred into the Drilling Information System database. The present dataset forms the basis for the digital lithologic columns and composite plots archived under the titles \"Visual core description of IODP Hole 386-M0091A\". […]本数据集包含国际大洋发现计划（International Ocean Discovery Program, IODP）386次航次（日本海沟古地震学研究）指定钻孔的岩性剖面单元描述内容。本数据集内容源自沉积物学家在386次航次陆上作业阶段（2022年2月14日至2022年3月15日，搭载"地球"号钻探船（D/V Chikyu）开展）所完成的可视化岩心描述（Visual core descriptions, VCD）工作。为实现信息数字化，研究人员将手绘可视化岩心描述表单的内容录入钻探信息系统（Drilling Information System）数据库。本数据集是以此前以"Visual core description of IODP Hole 386-M0091A"为标题归档的数字化岩性柱状图及综合图件的核心编制依据。[…]
