Peter Brimblecombe and Alla Yu. Lein, eds., Evolution of the Global Biogeochemical Sulphur Cycle (New York: Wiley, 1990).

This book was published on behalf of the Scientific Committee on Problems of the Environment (SCOPE) of the International Council of Scientific Unions (ICSU). In Chapter One "Evolution of the Sulphur Cycle in the Precambrian," M. Schidlowski described the geochemical cycle of sulphur as "one of those elemental cycles that appear to be basically controlled by life processes." He contributed research to show that this has been over most of the Earth's history.

The sulphur cycle constitutes one of the most striking examples of the impact the biosphere has exerted on the chemistry of the Earth's crust. Continuous biological processing of sulphur is ultimately responsible for dividing its movement from the surface environment to the rock strata--that is between the cycle of an organic and an inorganic reservoir.
