Description
Biogeochemical cycles of carbon, sulfur, nitrogen, phosphorus, calcium, and strontium will be discussed, and changes of reservoirs and reactions over geologic time as well as interactions between cycles will be examined. The elements discussed are important for the evaluation of global change and its effects on the biosphere and lithosphere. Recent anthropogenic perturbations of individual biogeochemical cycles will be evaluated and compared with perturbations known from the geologic past. The evolution of biogeochemical cycles will be evaluated in the context of petroleum systems, focusing on the temporal and spatial distribution of source rocks and reservoirs.
