Fig. 6: Three-stage evolution of magmatic and metamorphic CO2 outgassing rates.
From: India-Asia collision as a driver of atmospheric CO2 in the Cenozoic
Each filled red and yellow dot denotes a calculation result of the magmatic and metamorphic CO2 outgassing rate by CCFM, respectively, based on a set of geochemical data (including major element, trace element and Sr–Nd–Pb isotope composition) of each sample from 287 samples (for detailed calculation procedures see “Methods” and Supplementary Data 2), which have been distributed in 55 volcanic fields in Tibetan Plateau in the Cenozoic (Fig. 1). 1 Pg = 1015 g.
