Enhanced wildfire at the Frasnian-Famennian boundary and its implications for O2 level and F-F mass extinction: evidence from organic petrology and Os isotope stratigraphy

In this study, organic petrology and Osmium isotope (187Os/188Os) stratigraphy, major and trace element, and programmed pyrolysis analysis were performed on five...本研究对五个试样开展了有机岩石学（Organic Petrology）、锇同位素（Osmium Isotope，187Os/188Os）地层学、主量与微量元素以及程序升温热解分析。
