Biomarker evidence of algal-microbial community changes linked to redox and salinity variation, Upper Devonian Chattanooga Shale (Tennessee, U.S.A.)

This dataset includes carbon and sulfur data, major- and trace-metal data and biomarker data. The carbon and sulfur data were analyzed by an Eltra 2000 C-S analyzer at the University of Cincinnati. The major- and trace-metal data were analyzed by an ICAP-Q quadrupole ICP-MS at Arizona State University. The biomarker data were analyzed in Molecular Geobiology Lab in China University of Geosciences (Wuhan).
