Orientation data to reconstruct a stress state, and Raman spectrum data used to identify serpentine mineral phase and to estimate a metamorphic peak temperature

Dataset includes orientation data 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” is orientation data obtained from the Takami River Section, including the foliation in the Kogurisu Unit, the boundary between the Nakaguro Serpentinite (altered to the talc rock) and the Kogurisu Unit at sites A and B, talc veins in the Nakaguro Serpentinite at the site A, and carbonate veins in the metasomatized basalt blocks of the Kogurisu Unit at sites A and B. The vein data were applied to 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).
