High rates of rock organic carbon oxidation sustained as Andean sediment transits the Amazon foreland-floodplain
The oxidation of organic carbon contained within sedimentary rocks (“petrogenic” carbon, or
hereafter OCpetro) emits nearly as much CO2 as is released by volcanism, thereby playing …

Sulfur isotopes in rivers: Insights into global weathering budgets, pyrite oxidation, and the modern sulfur cycle
The biogeochemical sulfur cycle is intimately linked to the cycles of carbon, iron, and
oxygen, and plays an important role in global climate via weathering reactions and aerosols …

Neogene cooling driven by land surface reactivity rather than increased weathering fluxes
The long-term cooling, decline in the partial pressure of carbon dioxide, and the
establishment of permanent polar ice sheets during the Neogene period, have frequently …

Effects of carbonate minerals and exogenous acids on carbon flux from the chemical weathering of granite and basalt
The chemical weathering of silicate rocks can yield bicarbonate which is transported via
rivers to the ocean, followed by the deposition of carbonate, acting as a carbon sink on long …
