Stoer Group and Sibley Group nitrogen geochemistry in red beds (NERC Grant NE/V010824/1)
Nitrogen abundances in red shales are shown to be suitable as a biosignature that may be applicable to red beds on Mars. The data set includes organic carbon and nitrogen abundances and isotopic ratios, carbonate carbon and oxygen isotope ratios, and metal abundances. We evaluate potential abiotic effects and discuss diagenetic scenarios that lead to an enrichment of ammonium in clay minerals.

Organic carbon and nitrogen isotopes were analysed on decarbonated rock powders by EA-IRMS at the University of St Andrews. Carbonate carbon and oxygen isotopes were analysed by Iso-Analytical on bulk powders by gas-bench IRMS. Metal abundances were measured by ALS on bulk powders by ICP-MS and ICP-OES following digestion in HNO3, HCl, HF and HClO4.
