a Atmospheric pCO2 level. b Silicate weathering flux. The gray shaded rectangle represents the interval of intense chemical weathering (ICW), yielding elevated silicate weathering fluxes. The horizontal dashed lines represent the background values of atmospheric pCO2 (a) and silicate weathering flux (b) before the CAMP eruptions.
