An introduction to common stratigraphic and sedimentological tasks, and some basic theory
Posts here present an introduction to common stratigraphic and sedimentological tasks, such as recognizing and measuring sedimentary structures and stratigraphic sections in the field, describing sediments and sedimentary rocks, and the basic principles of sedimentation.
