Data for quantifying volcanism during Oceanic Anoxic Event 2 constrained by sedimentary mercury

This supporting information provides the details of the analytical methods (Text S1), the raw geochemical data of the studied samples (Table S1), the structure diagram of the model used in this study (Figure S2), and the model parameters (Tables S2 and S3). The detailed information on the global sites with Hg data (Figure S1), high-resolution Hg/TOC data during OAE 2 (Figure S3), the calculation of Hg enrichment factors (Hg-EF) (Figure S4, S5, and Table S4), and the evaluation of volcanic Hg input in the Qiangdong section (Figure S6, S7) are also provided here.
