DOI: 10.1016/j.marpetgeo.2019.06.027
Abstract: Abstract Nitrogen isotope (δ15N) analysis has been used to evaluate depositional redox conditions in well-preserved sedimentary systems; however, fewer N-isotope studies have been performed to reconstruct the redox conditions in lacustrine shales. In this paper,… read more here.
