Structural data to reconstruct a paleostress state, and Raman spectroscopic data used to identify serpentine minerals and to estimate a metamorphic peak temperature.

Dataset includes structural and Raman spectroscopic data obtained from the Nakaguro Serpentinite and the Kogurisu Unit of the Cretaceous Shimanto Accretionary Complex in the central Kii Peninsula, SW Japan. An open file in “1. Orientation data” are orientation data including the foliation in the Kogurisu Unit obtained from the Takami River Section, the boundary between the Nakaguro Serpentinite (altered to the talc rock) and the Kogurisu Unit from the sites A and B in the Takami River Section, talc veins in the Nakaguro Serpentinite from the site A, and carbonate veins in the metasomatized basalt block of the Kogurisu Unit from the sites A and B. The vein data can be analyzed by the stress inversion method (Yamaji & Sato, J. Struct. Geol., 2011, https://doi.org/10.1016/j.jsg.2011.05.006) using a GArcmB software (Yamaji, Isl. Arc, 2016, https://doi.org/10.1111/iar.12135). Open files in "2. Srp Raman data" are Raman spectrum data of serpentine from the Nakaguro Serpentinite. Open files in “3. RSCM data” are Raman carbonaceous-material spectrum data from a pelitic phyllite of the Kogurisu Unit. The data can be analyzed using the code proposed by Kaneki and Kouketsu (Isl. Arc, 2022, https://doi.org/10.1111/iar.12467) or PeakFit ver. 4.12. All open file data have been used in Shimura et al. (submitted to Tectonics).本数据集涵盖采自日本西南纪伊半岛中部白垩纪四万十增生杂岩（Cretaceous Shimanto Accretionary Complex）的中黑部蛇纹岩（Nakaguro Serpentinite）与小栗栖岩系（Kogurisu Unit）的结构数据及拉曼光谱数据。 "1. 定向数据"文件夹中的开放文件包含定向数据，具体包括：高见河剖面（Takami River Section）中小栗栖岩系的面理构造；高见河剖面A、B点位处中黑部蛇纹岩（已蚀变为滑石岩）与小栗栖岩系的接触边界；A点位处中黑部蛇纹岩内的滑石脉；以及A、B点位处小栗栖岩系交代蚀变玄武岩岩块内的碳酸盐脉。上述脉体数据可借助GArcmB软件，通过应力反演方法（Yamaji与Sato，《构造地质学报》，2011，https://doi.org/10.1016/j.jsg.2011.05.006）进行分析（Yamaji，《岛弧》，2016，https://doi.org/10.1111/iar.12135）。 "2. 蛇纹石拉曼数据"文件夹中的开放文件为中黑部蛇纹岩中蛇纹石的拉曼光谱数据。 "3. RSCM（碳质物质拉曼光谱）数据"文件夹中的开放文件为小栗栖岩系泥质千枚岩中的碳质物质拉曼光谱数据。该数据可采用Kaneki与Kouketsu提出的分析代码（《岛弧》，2022，https://doi.org/10.1111/iar.12467）或PeakFit v4.12软件进行解析。 本数据集所有开放文件中的数据已应用于Shimura等人的研究（投稿至《Tectonics》）。
