Dataset supporting the paper “Desiccation of the Red Sea basin at the start of the Messinian salinity crisis was followed by major erosion and reflooding from the Indian Ocean” (submitted to Communications Earth &amp; Environment). It contains ⁸⁷Sr/⁸⁶Sr results and derived ages for Wells A and B, image files used in Figures 2–5, and ArcGIS shapefiles used to build map figures.Contents:<b>Table 1_Sr data.xlsx</b>: Sr isotope data used in Table 1 and Figure 1 of the paper. (Ages calculated from measured ⁸⁷Sr/⁸⁶Sr using linear regression to the McArthur &amp; Howarth GTS2020 seawater curve.)<b>Figure 2c</b>: Core and macro images used for Figure 2 of the paper.<b>Figure 3</b>: Thin‑section images used for Figure 3 of the paper. Scale bar = 0.5 mm in each image.<b>Figure 4:</b> Well B and outcrop images used for Figure 4 of the paper.<b>Figure 5:</b> Seismic sections used for Figure 5 of the paper. Display: zero‑phase reverse polarity; vertical exaggeration = 4×.<br><b>ArcGIS Shapefiles</b> (map layers) used for the maps:mid ocean ridge axis (polyline)Oceanic Crust (polygon)Subsurface extent of Masiyah salt (polygon)Volcanic Vents (points)

本数据集支撑已投稿至《通讯-地球与环境》（Communications Earth & Environment）的论文《墨西拿盐度危机初期红海盆地干涸后经历大规模侵蚀与印度洋海水复侵》。数据集包含A井与B井的⁸⁷Sr/⁸⁶Sr比值测试结果及衍生年龄数据、论文中图2至图5所用图像文件，以及用于绘制地图图件的ArcGIS地理信息系统（ArcGIS）形状文件。

具体内容如下：
<b>Table1_Sr数据.xlsx</b>：论文表1与图1所用的锶同位素数据，其年龄通过实测⁸⁷Sr/⁸⁶Sr比值，结合McArthur与Howarth提出的GTS2020海水同位素曲线经线性回归计算得到。
<b>图2c</b>：论文图2所用的岩心与宏观图像。
<b>图3</b>：论文图3所用的薄片图像，每张图像的比例尺均为0.5 mm。
<b>图4</b>：论文图4所用的B井与露头图像。
<b>图5</b>：论文图5所用的地震剖面，显示参数为：零相位反极性；垂直放大倍数为4×。
<b>ArcGIS形状文件</b>（地图图层）：
- 洋中脊轴（多线段）
- 洋壳（多边形）
- 马西亚盐层的地下分布范围（多边形）
- 火山喷口（点要素）
