Sediments and sedimentary rocks are fundamental to our understanding of the Earth and the array of environments that characterise its surface. Since some 70% of the rocks on the Earth’s surface are sedimentary in origin and sediments are of great economic importance, there is a very good chance that we encounter a sedimentary rock or an associated sedimentary process at some point every day of our lives.                   Introducing Sedimentology covers all the rudimentary aspects of sedimentology including different types of sedimentary rocks, sedimentary structures, and environments of deposition of sediments. The application of sedimentology in the search for valuable economic resources is explained and how sedimentary rocks play a key role for subsurface storage of carbon dioxide and hydrogen as part of the low-carbon energy transition.                                                                   Written for students, amateur enthusiasts and professional geologists, Introducing Sedimentology provides a succinct and accessible introduction to the science of sedimentology. It is generously illustrated with many explanatory line diagrams and colour photographs.
