Portion of title Microbial mats in sandy deposits from the Archean era to today
Contents Introduction. Microbial mats, stromatolites and MISS : an overview -- The geobiological concept -- Microbially induced sedimentary structures (The scholarly definition ; Taxonomic relation of MISS to stromatolites ; Etymology of the term ; History of MISS research ; Distribution of MISS in space and through time (Temporal distribution ; Spatial distribution) -- Significance of MISS : status and perspectives. Sedimentology (Biotic-physical sediment dynamics versus physical sediment dynamics ; A new group of primary sedimentary structures ; Indicators for sequence stratigraphy and basin analysis) ; Paleontology and microbiology (First cyanobacteria ; First photoautrophic microbiota) ; Astrobiology (Earthly analogues ; Biosignatures) ; Oceanography and climatology -- Collection of MISS -- Concepts. MISS : products of life and environment. (The sedimentary surface : an interface (The three main types of sedimentary systems) ; Life at the interface (Biofilm ; Microbial mat ; Cyanobacteria for beginners) -- Formation and preservation of MISS. Development and preservation of microbial mats : the ecological and the taphonomic window (The ecological window : primary processes of MISS-formation ; The taphonomic window : primary and secondary processes of MISS-preservation) ; Bringing the ecological and taphonomic window into alignment : the search for biofilms and microbial mats in siliclastic settings (Search ; Detection ; Identification ; Confirmation ; Differentiation) ; The criteria for biogenicity of MISS (List of criteria ; The criteria for the biogenicity of MISS in the context of the criteria for stromatolites) --
Contents Classification. The classification diagram of MISS -- The five categories of MISS. Structures arising from microbial growth (Oriented grains ; Laminated leveling structure) ; Structures arising from microbial binding (Mat microfabrics ; Sinoidal structure) ; Structures arising from biostabilization (Mat chips ; Roll-up structure ; Shrinkage cracks ; Petees ; Gas domes ; Sponge pore fabrics) ; Structures arising from baffling and trapping (Mat layer-bound small grains ; Mat layer-bound heavy minerals) ; Structures arising from the interference of all microbial activities interacting with physical sediment dynamics (Erosional remnants and pockets ; Multidirected ripple marks ; Microsequences ; Wrinkle structures ; Polygonal oscillation cracks) -- Application. Ancient biofilm- and microbial mat-forming prokaryotes ; Geobiological field trip sites. Modern and Pleistocene catena of benthic cyanobacteria in the Bahar Alousane, southern Tunisia, Africa ; Earth's possibly oldest fossil-cyanobacteria preserved in the Nhlazatse section, 2.9 Ga Pongola Supergroup, South Africa (Location of the outcrop ; Stratigraphy ; Tectonic overprint ; Biofilm-catena ; Exceptionally preserved structures in the Nhlazatse outcrop).
Review "This book describes microbial mats that occur in sandy marine environments from 3.2 billion years ago to the present. It gives an overview of the growth and development of microbial mats in modern settings, the interaction of microbial mats with physical sediment dynamics, and the formation and preservation of microbially induced sedimentary structures. These structures are much more common than stromatolites, and are abundant throughout Earth history. They constitute a significant archive for the understanding of Earth's earliest environments, and are important as biosignatures in the detection of life on other planets. This book is for sedimentologists, paleontologists, microbiologists, and geobiologists."--BOOK JACKET.
