• W4254751036 abstract "<strong class=journal-contentHeaderColor>Abstract.</strong> Growing evidence points to the dynamic role that kerogen is playing on Earth's surface in controlling atmospheric chemistry over geologic time. Although quantitative constraints on the weathering of kerogen remain loose, its changing weathering behavior modulated by the activity of glaciers suggests that this largest pool of reduced carbon on Earth may have played a key part in atmospheric <span class=inline-formula>CO₂</span> variability across recent glacial–interglacial cycles and beyond. This work enunciates the possibility of kerogen oxidation as a major driver of atmospheric <span class=inline-formula>CO₂</span> increase in the wake of glacial episodes. This hypothesis of centennial- and millennial-timescale relevance for this chemical weathering pathway is substantiated by several lines of independent evidence synthesized in this contribution, including the timing of atmospheric <span class=inline-formula>CO₂</span> increase, atmospheric <span class=inline-formula>CO₂</span> isotope composition (<span class=inline-formula>¹³C</span> and <span class=inline-formula>¹⁴C</span>), kerogen oxidation kinetics, observations of kerogen reburial, and modeling results. The author hypothesizes that the deglaciation of kerogen-rich lithologies in western Canada contributed to the characteristic deglacial increase in atmospheric <span class=inline-formula>CO₂</span>, which reached an inflection point <span class=inline-formula>≤</span> 300 years after the Laurentide Ice Sheet retreated into the kerogen-poor Canadian Shield. To reconcile the release of isotopically light carbon via kerogen oxidation with Earth surface carbon pool constraints, major oceanic degassing and biospheric regrowth must have acted in concert across glacial–interglacial transitions. Additionally, a process such as a strong shift in the ratio of <span class=inline-formula>C₃</span> to <span class=inline-formula>C₄</span>-derived organic matter must be invoked to maintain isotope mass balance, a point key for reconciling the hypothesis with the carbon isotope record of marine dissolved inorganic carbon. In order to test this hypothesis, quantitative constraints on the contribution of kerogen oxidation to <span class=inline-formula>CO₂</span> rise at glacial terminations are needed through systematic studies on (1) <span class=inline-formula>CO₂</span> fluxes emanating from the weathering of different lithologies, (2) oxidation kinetics of kerogen along glacial chronosequences, and (3) high-resolution temporal changes in the aerial extent of glacially exposed lithological units and glacial flour." @default.
