Influence of climate and the expansion of C4 grasses on sequence-scale cyclicity and landscape development during the late Miocene to Pleistocene of West Texas.
… two drill cores reveals sequence-scale trends in paleosol maturity, cycle thickness, and facies proportions. Stable isotope geochemistry of bulk paleosol samples and pedogenic carbonate suggest C₄ expansion at 7.25 Ma and provide a pCO₂ reconstruction of the late Miocene to Pleistocene. C₄ onset …
