Pulsed Vertical Displacement and Subsequent Shearing in the Forearc of the Costa Rican Convergent Margin: Evidence from Paleomagnetic Results of IODP Site U1413: Datasets and Supplementary materials

This dataset is published along with the paper "Xu, S.H., Zhao, X.X., Li, Y-X.*, Liu, X.Y., Chen, W.W., 2021. Pulsed Vertical Displacement and Subsequent Shearing in the Forearc of the Costa Rican Convergent Margin: Evidence from Paleomagnetic Results of IODP Site U1413. Marine Geology, https://doi.org/10.1016/j.margeo.2021.106606 " The dataset contains the characteristic remanent magnetization (ChRM) data (Table 1) and the 90-Kmin data (Table 2) of IODP Site U1413 samples. Kmin is the minimum axid of the anisotropy of magnetic susceptibility data. The dataset also includes three supplementary figures. Fig. S1 shows the newly refined magnetostratigraphy of this study supercedes that obatined during the expedition. Fig. S2 shows the age-depth model based on the refined magnetostratigraphy and the biostratigraphy of Site U1413. Fig. S3 shows the comparison of the downcore changes of 90°-Kmin values of the middle slope site U1380 and the upper slope site U1413.

本数据集随论文《Xu, S.H., Zhao, X.X., Li, Y-X.*, Liu, X.Y., Chen, W.W., 2021年，科斯塔黎加会聚边缘弧前区的脉冲式垂向位移与后续剪切作用：来自综合大洋钻探计划（Integrated Ocean Drilling Program, IODP）U1413站点古地磁结果的证据》，《海洋地质学》，https://doi.org/10.1016/j.margeo.2021.106606》一同发布。数据集包含综合大洋钻探计划U1413站点岩芯样品的特征剩磁（characteristic remanent magnetization, ChRM）数据（表1）与90°-Kmin数据（表2），其中Kmin指磁化率各向异性（anisotropy of magnetic susceptibility）数据的最小主轴。本数据集还包含3幅补充图：图S1展示了本研究最新厘定的磁地层学，该成果取代了本航次获取的磁地层学结果；图S2展示了基于厘定后的磁地层学与U1413站点生物地层学构建的年龄-深度模型；图S3展示了中坡站位U1380与上坡站位U1413的90°-Kmin值沿岩芯向下变化特征的对比。
