This is a geochemical dataset accompanying Emmings, J., Poulton, S., Vane, C., Davies, S., Jenkin, G., Stephenson, M., Leng, M., Lamb, A., Moss-Hayes, V. A Mississippian Black Shale Record of Redox Oscillation. Palaeogeography, Palaeoclimatology, Palaeoecology [submitted July 2019]. This dataset includes RockEval pyrolysis, major and trace element (XRF), Fe speciation, C, N and S isotopes and S species analyses through the Upper Bowland Shale in the Craven Basin (Lancashire, UK). This research was conducted by Joe Emmings, PhD researcher at the University of Leicester and British Geological Survey (BGS) between 2014-2018, and as a post-doctoral research associate (PDRA) at the British Geological Survey (2018-2021). The PhD research was funded by the Natural Environment Research Council (NERC), as part of the Central England Training Alliance (CENTA) [grant no. NE/L002493/1] and received CASE funding from the BGS. PDRA research was funded by the British Geological Survey.
