Book excerpt: Black shales provides the first comprehensive synthesis of the diverse research regarding the origin of petroleum source rocks. The book offers in-depth reviews from the fields sedimentology, palaeoecology, and geochemistry, and particularly focuses on the influence of palaeo-oxygen levels. Current debates--including the one over the influence of sedimentation rate, productivity, and enhanced preservation on the burial efficiency of organic carbon--receive a lively discussion. In addition, the importance of newly defined concepts of sequence stratigraphy to models of the formation of black shales receives an in-depth treatment for the first time. The book will be of interest to all geologists investigating palaeoenvironments, particularly those engaged in the search for hydrocarbons.
