Crustal carbon. In contrast to the noble gases, carbon near the planetary surface is concentrated in crustal rocks, and is largely divided between carbonates, with an isotopic composition of = Q%c and sedimentary organic carbon with = -25%c. While Hoefs (1969) estimated a total of 2.6 X 10 g of C, with 66% in sedimentary rocks, Hunt (1972) reassessed the budget using sedimentary rock abundance data from Ronov and Yaroshevsky (1969) and carbon concentration data compilations to obtain a higher value of 9 X 10 g. Ronov and Yaroshevsky (1976) updated their earlier work with new additional data to obtain a... 

Global sedimentary budget. Finally, on a global scale, we point to an interesting model by Berner and Canfield (1989), which took as a given an organic carbon and reduced sulfur concentration of sediments of different type (nearshore sands, offshore clays, abyssal clays, etc.). In this view, a net source or sink of O2 to the atmosphere could be driven by rearrangement of the sedimentary rock mass of the Earth, from abyssal clays to nearshore clays, for example.
