Salt Tectonics in Sedimentary Basins: Applications to Earth Sciences, Basin Analysis, Petroleum and Mineral Exploration aims to introduce the subject to a broad audience of earth scientists who are not specialists in salt tectonics but wish to acquire a broad, global knowledge and understand the basic principles of evaporite deposition and salt tectonics as applied to earth sciences, basin analysis, petroleum and mineral exploration. The scope of this volume is to start from basic chemistry and physics principles discussing the mineralogy and fundamental chemical and physical properties of evaporites, then advance to the analysis of depositional environments in sedimentary basins worldwide where evaporites have been deposited in the geological time.
Volume highlights include:
- Objectives and contents that can fill the need of many earth science students and professionals, focusing on understanding basic salt tectonics principles in sedimentary basins worldwide and presenting its application to petroleum industry
- Concepts about evaporite deposition and salt tectonics that have been developed in the past 50 years, paving the way for petroleum exploration in deep water provinces in many salt basins wordwide, such as the South Atlantic, the Gulf of Mexico and the Mediterranean Sea
- Integration of classic salt basins, geological and geophysical datasets and their petroleum plays with plate tectonics concepts
Salt Tectonics in Sedimentary Basins is a valuable resource for undergraduate and graduate students, particularly young professionals working on basin analysis applied to petroleum exploration studies in Atlantic-type sedimentary basins.
