Abstract: (Significance)The Permian-Triassic transition was characterized by severe climatic and environmental perturbations, accompanied by the largest mass extinction event in the Phanerozoic. The Siberian Traps Large Igneous Province, the largest continental large igneous province in Earth history, is widely considered to be the ultimate trigger of this ecological crisis. (Methods)However, although sedimentary rocks preserve abundant environmental and biological signals, they generally lack direct records of volcanic activity, which has long hindered high-resolution investigations of the causal relationships among volcanism, environmental perturbations, and biotic crises during this interval. A critical challenge, therefore, lies in tracing signals of ancient volcanic activity within sedimentary successions. (Results)Taking the intense volcanism at the Permian-Triassic boundary as a representative case, this study reviews volcanic proxies preserved in stratigraphic records, including volcanic lava and ash (tuff) layers, volatile components (e.g., carbon, mercury, and sulfur), and non-volatile components (e.g., metallic elements such as copper, zinc, and nickel). The results indicate that these proxies exhibit pronounced signals saddle the Permian-Triassic boundary strata, suggesting that volcanic eruptions exerted significant impacts on surface elemental cycles. (Conclusions)Furthermore, the advantages and limitations of different proxies are evaluated, providing a reference for future deep-time volcanic tracing studies and offering perspectives on future research directions.
