The third edition is devoted to the task of describing and classifying the various families of sedimentary rocks and to an understanding of their textures and structures. Beyond this description there is a brief statement on origin insofar as it can be deduced from the relevant field and laboratory observations No attempt is made to explore the physics or chemistry of the formative processes. In general the emphasis has moved away from thin-section analysis of sedimentary rocks (though this remains an important topic) to a closer look at the outcrop and the utilization of both sedimentary structures and the vertical profile or sequence in sedimentary analysis.
