Fig. 7: Pressure-temperature (P-T) trajectories for pelitic granulites in Palaeoproterozoic orogens.
From: Increased biomass and carbon burial 2 billion years ago triggered mountain building
Typically, trajectories pass from hot (>800 °C) temperatures (red circles) during crustal thickening to cooler temperatures (blue circles) during exhumation. Note range of timescales from thickening to exhumation from rapid to over a billion years. Trajectories from published sources53,54,55,56,57,58,59,60.
