Evaporites through Space and Time - Special Publication no 285 (Geological Society Special Publication)

This book is an exploration of varying approaches to the study of the deposition, diagenesis and stratigraphy of evaporites. The volume includes papers from chemical modellers, who work on the basis of geochemical representations of the formative water bodies, and from basin-wide depositional-stratigraphical modellers, who propose depositional scenarios that are fitted to individual basinal pictures. Until now there have been only a few studies of evaporite formation that explain the characteristic features we observe in the real rock record. This volume is a collection of relevant papers in which these features are integrated in a realistic manner, based on our new understanding of saline water bodies, to the diverse tectonic, chemical and depositional constraints of their individual basins. In additional there are several review articles that offer oversight and extensive referencing of basins worthy of further study. This book is a valuable resource for sedimentologists and stratigraphers looking for an up-to-date reference on evaporite deposits.Also available: Non-Marine Permian Biostratigraphy and Biochronology - ISBN 1862392064 Cool-Water Carbonates: Depositional Systems and Palaeoenvironmental Controls - ISBN 1862391939 Geometry and Petrogenesis of Dolomite Hydrocarbon Reservoirs - ISBN 1862391661

during The Past Decade, Work On Cool-water Carbonates Has Expanded To Become A Mainstream Research Area. Studies On Modern And Quaternary Deposits Will Continue To Be Important; However, There Is Increasing Momentum Towards Unravelling Sediment Processes, Biota Sediment Interactions And Diagenetic Products In Cenozoic And Older Cool-water Carbonates. Many Contributions In This Book Document Cenozoic And Quaternary Carbonates From Landlocked (microtidal) Water-bodies. These Carbonates Display Important Differences In Biota And Fabric Distributions When Compared With World Ocean Examples. Consequently, The Scientific Community Is Now Better Placed To Reinterpret Pre-tertiary Carbonates Where There Is A Suspicion That They Have Developed Under Microtidal Conditions. Some Papers In The Book Provide New Approaches To Interpreting Environmental Change Within Macrotidal Regimes And Others Lay Firm Foundations For Future Cool-water Carbonate Diagenetic Research.

the Aim Of The Book Is To Illustrate Recent International Contributions To Cool-water Carbonates Research, With An Emphasis On Neogene And Recent Case Studies. Contributions Are Divided Into Three Sections: Microtidal Carbonates From The Mediterranean Realm; Macrotidal Examples From New Zealand, Australia And Mexico; And Early Diagenetic Fabrics.

The wide distribution of dolomite rocks in North American, Middle- and Far-Eastern hydrocarbon reservoirs is reason enough for their intensive study. In this volume dolomite enthusiasts review progress and define the current boundaries of dolomite research, related particularly to the importance of these rocks as reservoirs. As might be expected, reviews provide critical analyses of past ideas on origins and why many are no longer tenable. Discussions range between conceptual models and numerical simulations of the flow paths of dolomitizing fluids, geochemical modelling, and microbial mediation. Case studies from areas as diverse as North America, the Middle East, South-east Asia and Australia provide a solid background but illustrate important differences in views on the origins of these enigmatic rocks The Permian period (251 to 299 Ma) encompasses nine ages (stages) arranged into three epochs (series). Most of the Permian marine timescale has been defined by global stratotype sections and points for the stage boundaries. This volume presents new data regarding the biostratigraphy and biochronology of the non-marine Permian and provides a basis for temporally ordering Permian geological and biotic history on land, and correlating that history to events in the marine realm Cover ......Page 1 Cover......Page 2 Front matter......Page 3 Contents......Page 7 1......Page 9 15......Page 22 37......Page 43 53......Page 59 69......Page 75 87......Page 92 107......Page 111 143......Page 147 155......Page 159 169......Page 173 179......Page 183 191......Page 195 219......Page 223 247......Page 251 265......Page 269 275......Page 278 285......Page 288 309......Page 312 335......Page 338 Index......Page 368 During the past decade, work on cool water carbonates has expanded to become a mainstream research area.
