7.7 The Earliest Phosphorites: Radical Change in the Phosphorus Cycle During the Palaeoproterozoice macro-molecules are involved in energy transport, information storage, and structural support functions include membrane lipids, proteins, and nucleic acids. The global phosphorus cycle, which includes only dissolved and solid phases without any gaseous components, is strongly influenced by biolog

7.10 Chemical Characteristics of Sediments and Seawater (Holland 2006) transformed the biogeochemical cycles of the elements by imposing an oxidative step in the cycles, creating strong redox gradients in the terrestrial and marine realms that energised microbial metabolism. Although much past research was focused on establishing when the rise of atmosp
