ALBERT

Description / Table of Contents: "The geochemistry and chemistry of sulfur, iron and iron sulfides in sedimentary systems is reviewed. Sulfur microbiology is described and the microbial ecology of sulfidic sediments is discussed. Sulfur and iron stable isotope biochemistry is addressed against the background of recent advances in this field with respect to sedimentary and microbial systems. Environmental aspects of the present sedimentary sulfur cycle are considered with special references to the development of euxinia and global anoxic events. The biogeochemistry of ancient sulphur-rich sediments is considered and the evolution of the sedimentary sulfur system is discussed against the background of the evolution of the Earth surface environment. The evolution of the sulfur biome and its impact of the early development of life on Earth are discussed."--Cover
