Supplementary data of Differential microbial degradation of organic matter in the late Mesoproterozoic ocean with in-situ micro-Raman analysis

This supplementary dataset provides comprehensive geochemical and Raman spectroscopic data from the ~1250 Ma Taizi Formation of the late Mesoproterozoic Shennongjia Group. Table S1. Comprehensive geochemical dataset of the Taizi Formation, including bulk measurements of total organic carbon (TOC), total nitrogen (TN), carbon and nitrogen isotopic compositions (δ¹³Corg, δ¹⁵N), iron speciation data, and trace element concentrations. Table S2. In-situ Raman spectral data of organic matter, consisting of 733 individual spectra with corresponding baseline-corrected peak fitting results and calculated Raman parameters (e.g., I₁₃₅₀/I₁₆₀₀, FWHM-D1).
