Microbial SedimentsMicrobes are of key importance in the production, deposition and diagenesis of sediments. This volume provides a comprehensive overview of microbial sediments. It contains authoritative and stimulating contributions by distinguished authors that cover the field and set the scene for future advances. It deals with mats and biofilms, biosedimentary precipitates, fabrics and diagenesis in a wide range of sedimentary environments, and it examines the development of microbial sediments through time. It is designed for postgraduate researchers and professional scientists who require up-to-date information on the influence of microorganisms on sedimentation. |
