Diagenesis and iron paleo-redox proxies: New perspectives from magnetic and iron speciation analyses in the Santa Barbara Basin
Sign Up to like & getrecommendations! Published in 2019 at "Chemical Geology"
DOI: 10.1016/j.chemgeo.2019.04.018
Abstract: Abstract Sedimentary redox proxies are usually employed to reconstruct the paleo-redox conditions of bottom water environments, assuming that porewater and bottom water dissolved oxygen concentrations are similar. Using a combination of geochemical and magnetic techniques,… read more here.
