Iron mineral evolution as an important geobiological driver of deep-time carbon sequestration in coal systems

This dataset includes previously published geochemical data from the Yinshan Orogenic Belt, as well as new data on proximate analyses, total sulfur contents, vitrinite random reflectance, microscopic maceral compositions, organic carbon isotope values, and major element concentrations of coal samples. The geochemical data from the Yinshan Orogenic Belt cover Neoarchean granitoids, Neoarchean–Paleoproterozoic granitoids, Paleoproterozoic granitoids, and Paleoproterozoic diorites. The specific sources of these published data are listed in the caption of Figure 4. Together, these datasets provide constraints on the provenance of iron in the Qinshui Basin.本数据集包含此前已发表的阴山造山带（Yinshan Orogenic Belt）地球化学数据，以及煤样品的工业分析、全硫含量、镜质体随机反射率、显微煤岩组分、有机碳同位素值和主量元素浓度等新测试数据。阴山造山带的地球化学数据涵盖新太古代花岗岩类、新太古代-古元古代花岗岩类、古元古代花岗岩类以及古元古代闪长岩。上述已发表数据的具体来源详见图4的图注。综合上述数据集，可为沁水盆地（Qinshui Basin）中铁的物源研究提供约束。
