Calcium carbonate formation is the primary pathway by which carbon is returned from the ocean–atmosphere system to the solid Earth,. The removal of dissolved inorganic carbon …
Abstract The greater McArthur Basin is an informal term for a Palaeo-to-Mesoproterozoic sedimentary system that consists of terranes from the McArthur Basin, Birrindudu Basin, and …
While barium (Ba) and strontium (Sr) stable isotopes are increasingly used as tracers of biogeochemical processes and paleo-proxies, the role of biotic processes on Ba and Sr …

The relationship between silicate weathering, Tibetan Plateau uplift, and global cooling during the Cenozoic provides a valuable case study for understanding the interaction of …
The Atlantic is the only ocean basin almost entirely surrounded by passive margins, and a major global long‐term sink of carbonate carbon that has evaded subduction. Quantifying …
The barium isotope composition of sedimentary barite (BaSO 4, barium sulfate) is emerging as a powerful tracer of the sources and cycling of Ba in modern and ancient marine …
We measured barium attachment and detachment fluxes from and to barite crystal surfaces in solutions with [Ba]/[SO 4] ratios from 0.06 to 52. The doping of 137 Ba in the initial …
