I. I NTRODUCTION 1. Stratigraphy -- study of layered or sedimentary rocks and their distribution in space and time with goal of reconstructing the history of the earth. 2. Sedimentology - focuses on the processes that form sediments and includes the interpretation of sedimentary rocks on the microscopic and macroscopic scale. In fact, interpretation of depositional environments has become the key to nearly every stratigraphic study as more and more modern analogs for ancient stratigraphic sequences are studied. 3. The theme we will follow is how does a geologist go about interpreting the sedimentary rock record? Observation and description of the rocks are one important aspect. What those observations and features of the rocks mean is the next important step. Interpretation also depends on the theoretical framework that has been established for sedimentary rocks, for example Steno's Principles. We are going to start at the smallest scale, that of a grain and then work our way into bigger and bigger sedimentary rock packages.
