Aridity-driven decoupling of δ¹³C between pedogenic carbonate and soil organic matter [PDF]

, 2020
Pedogenic carbonate is an invaluable archive for reconstructing continental paleoclimate and paleoecology. The δ¹³C of pedogenic carbonate (δ¹³C_c) has been widely used to document the rise and expansion of C₄ plants over the Cenozoic.
