Fig. 1: Fluid–carbonate mineral interactions in the deep carbon cycle.

From: Deep carbon cycle constrained by carbonate solubility

Fig. 1

White headed black arrows indicate carbonate flux and blue arrows water flux. Blue shaded areas indicate water-rich regions. The melting of carbonated igneous oceanic crust is not shown as it starts at depths of 300 km22. The image is to scale, apart from the thickness of oceanic sediments that has been exaggerated.
