Barium Isotopes Drivers, Dependencies, and Distributions through Space and Time Elements in Geochemical Tracers in Earth System Science Series
Langue : Anglais
Auteurs : Horner Tristan J., Crockford Peter W.
In the modern marine environment, barium isotope (?138Ba) variations are primarily driven by barite cycling?barite incorporates 'light' Ba isotopes from solution, rendering the residual Ba reservoir enriched in 'heavy' Ba isotopes by a complementary amount. Since the processes of barite precipitation and dissolution are vertically segregated and spatially heterogeneous, barite cycling drives systematic variations in the barium isotope composition of seawater and sediments. This Element examines these variations; evaluates their global, regional, local, and geological controls; and, explores how ?138Ba can be exploited to constrain the origin of enigmatic sedimentary sulfates and to study marine biogeochemistry over Earth's history.
