Global chronostratigraphical correlation table for the last 2.7 million years v.2019 (Poster version)

This 'version 5' upload is the 2022-updated poster-version of Figure 1 of the Quaternary International 500 article (version 1).
The Figure 2 inset from that paper, is also included here, for completeness.
Cohen, K.M. & Gibbard, P.L. 2019 Global chronostratigraphical correlation table for the last 2.7 million years.

See abstract and full text of the linked paper for details, research history and citations/references to materials included in the chart: it makes extensive use of published data sets and schemes, all cited in the main text, many of which have data repositories.

The 2020 update comprised the ratification of a GSSP for the Middle Pleistocene (introducing the Chibanian Stage), the splitting of the Subseries and Stages column and the way the GSSPs are indicated, and the lowering of the provisional numeric age for the Late Pleistocene Subseries/Stage from 0.129 to 0.126 (affecting the dashed horizontal line that serves as a left-right guide across the chart). The 2021 update corrected a MIS misnumbering at the top of the Olduvai (63, 65) present in older editions, spotted after over a decade of updating the figure/poster. Otherwise, the undivided poster version only differs from the 3-page spread figure in the QI paper in placement and font size of title and version, placement of logotypes, inclusion of Utrecht University and University of Cambridge logo's on the poster (continued from earlier releases of the chart), reference to the Quaternary International v-500 2019 paper.
All data featured on the chart, is referenced in brief in the text below, and referenced in full and documented in brief in the 2019 paper.

The 2019 QI-500 paper publication followed up the Episodes 2008 Gibbard & Cohen paper.
The 2021 and 2020 edition of the chart (versions 4, 3, 2 in this repository) follow up editions in 2019 (QI-500/INQUA-Dublin; version 4) and the 2016 IUGS' Cape town IGC version (web-released at the time).
The 2021 and 2022 edition are corrigenda regarding MIS labeling around the Olduvai (see text in Steps to reproduce).

The release of the poster version via data.mendeley.com, cross-referenced from the QI paper, was coordinated with the QI journal management (Elsevier) and editorship (INQUA).
Use of the IUGS-ICS and INQUA logo's was coordinated with the respective organisations (and is continued from earlier releases of the chart).

The PDF files contain scale-able vector graphics only and therefore should suit reproductions to mini-poster (A4, A3) and poster size (e.g. A1) formats alike.
Before seeking far zoomed-in usage of the chart: take notice of the discussion in the QI paper of chosen graphical resolution, versus achievable geological and chronometric correlation accuracy limits.

本版‘第五版’上传内容为《第四纪国际》500期文章（版本1）中的图1的2022年更新版海报形式。该文中的图2插图亦一并收录，以臻完整。科恩（Cohen）和吉巴德（Gibbard）于2019年编制的过去270万年全球年代地层对比表亦包含其中。图1的详细信息、研究历史以及图表中包含材料的引用/参考文献，请参阅所链接论文的摘要和全文。该研究广泛使用了已发表的数据库和方案，所有引用均列于正文，其中许多具有数据存储库。

2020年的更新包括对中更新世全球界线层型（引入了千川阶）的批准、将子系列和阶别列的分割以及全球界线层型的指示方式，以及将晚更新世子系列/阶别的临时数值年龄从0.129降低至0.126（影响横跨图表的虚线水平线，作为左右引导）。2021年的更新纠正了旧版中奥杜瓦伊层顶部（63, 65）的MIS编号错误，该错误在经过十多年的图表/海报更新后被发现。否则，未分割的海报版仅与《第四纪国际》期刊中的3页版图在标题和版本的位置、标志的位置、包含乌德勒支大学和剑桥大学的标志（继承自早期发布的图表）以及引用《第四纪国际》v-500 2019年论文方面存在差异。

图表上所有数据均在下文简要提及，并在2019年的论文中进行了全面引用和简要说明。

2019年的《第四纪国际》500期论文发布是对2008年吉巴德（Gibbard）和科恩（Cohen）的《事件》论文的后续研究。2021年和2020年的图表版（在此存储库中的版本4、3、2）是2019年（QI-500/INQUA-Dublin；版本4）和2016年国际地层委员会（IUGS）开普敦国际地质大会版本（当时已网络发布）的后续版本。2021年和2022年的版本是关于奥杜瓦伊层MIS标签的勘误。

通过data.mendeley.com发布的海报版与《第四纪国际》论文进行了交叉引用，并得到了《第四纪国际》期刊管理（Elsevier）和编辑委员会（INQUA）的协调。IUGS-ICS和INQUA标志的使用与相应组织进行了协调（并继承自早期发布的图表）。

PDF文件仅包含可缩放的矢量图形，因此适用于迷你海报（A4、A3）和海报尺寸（例如A1）格式。在寻求图表的远距离放大使用之前，请注意《第四纪国际》论文中关于所选图形分辨率与可实现的地质和年代学相关性精度限制的讨论。
