The carbon isotopic signature of the upper mantle is heterogeneous
Abstract Knowledge of the carbon isotopic (δ13C) signature of the mantle source region of mid–ocean ridge basalts, is key to understanding carbon cycling on a planetary scale. This value has long been held at –4‰ from the study of popping rocks or –5‰ from the study of peridotitic diamonds, with lit...
