Stability of atmospheric CO[sub 2] levels across the Triassic/Jurassic boundary.

Examines the carbon isotope compositions of pedogenic calcite from paleosol formations spanning across the Triassic/Jurassic boundary to represent a rise in atmospheric carbon dioxide concentrations. Effects of the eruptions of the Central Atlantic Magmatic Province; Factors controlling carbon isotopic composition of soil carbonate; Stratigraphic units sampled; Calculation findings of atmospheric paleo-carbon dioxide.
