Introduction to Sequence Stratigraphy - SEPM .Översätt den här sidan

Thus the sequence stratigraphic framework is used to analyze and explain how sedimentary rocks acquire their layered character, lithology, texture, faunal associations and other properties. These properties in turn can be used to explain how the mechanisms of sediment accumulation, erosion and inter-related processes produced the current configuration of these rocks.
