The Field Description of Sedimentary RocksA practical volume that describes how the features of sedimentary rocks can be recorded in the field, particularly through the construction of graphic logs. Discusses such particular aspects of sedimentary rocks as lithology, texture, sedimentary structures, fossils and paleocurrents, with emphasis on what features to look for and how to measure and assess them for later environmental and process interpretation of facies, facies sequences, and facies associations. |
