Description

The enclosed dataset contains all of the raw data supporting the results presented in the paper titled: "Timing and provenance of volcanic fluxes around the Permian-Triassic Boundary Mass Extinction in South China: U-Pb zircon geochronology, volcanic ash geochemistry and mercury isotopes". 

The Excel data file contains four data sheets as follows: 

1. Table S1: This sheet contains the U-Pb output table from ETRedux. The data sheet contains all the U and Pb isotopic data generated for the current study.

2. Table S2: This excel sheet contains the geochemical compositions of analyzed volcanic ash beds as well as LOI-normalized major element compositions of these ashes.

3. Table S3: This excel sheet contains the other geochemical and isotope data for all analyzed samples. This includes Hg concentration and isotope compositions, TOC data, as well as major and trace element concentrations and ratios.

4. a final table containing the analyzed Hg isotope compositions for the utilized standard reference materials -  ETH Fluka, UM-Almaden, NIST 1632D and MESS-3.
