Many problems pertaining to Carbonate petrology can only be understood within the frame of the "tempo-spatial" evolution of the Earth as a whole. In this paper, the author introduces the idea of a mineralogical evolution of the Earth 's atmosphere and its bearing on both chemical and biochemical activities in the sedimentary environment.

The data are partially based an earlier works of different authors as well as on laboratory and fieldwork done by the author during the last two decades.
