Additional file 6: of The effects of meteoric diagenesis on the geochemical composition and microstructure of Pliocene fossil Terebratalia coreanica and Laqueus rubellus brachiopod shells from northeastern Japan

Figure S2. Sampling spots, δ13C and δ18O values, minor element (Mn, Fe, and Sr) concentrations, mean CL intensities, altered fiber ratios, and altered fiber and puncta-filling cement ratios of the modern (Figure S2-1, SGLR) and fossil (Figures S2-2–6, MNLR1–MNLR5) L. rubellus shells. Composite CL images are presented for each shell. SEM and CL images of selected shell portions are also shown. (ZIP 25125 kb)

补充图S2 展示了现生（补充图S2-1、SGLR组）与化石（补充图S2-2至S2-6、MNLR1至MNLR5组）赤子爱胜蚓（L. rubellus）壳体的采样点位、碳同位素比值（δ¹³C）与氧同位素比值（δ¹⁸O）、微量元素（锰Mn、铁Fe、锶Sr）含量、平均阴极发光（Cathodoluminescence, CL）强度、蚀变纤维占比，以及蚀变纤维与点隙充填胶结物的占比。所有壳体均配有复合阴极发光图像，同时还展示了所选壳体区域的扫描电子显微镜（Scanning Electron Microscope, SEM）及阴极发光图像。本补充材料为ZIP压缩包，大小为25125 KB。
