    Seismic, magneto-, bio- and chronostratigraphy; building the geological time scale.

Sedimentary rock is formed when mineral and organic particles (or sediment) are naturally cemented together. Because these rocks are the only ones to be built of accumulated components, they are the only rocks that trap the remains of past life (fossils). Because these rocks are the only ones to form at Earth’s surface, they serve a primary role in the study of ancient surface processes and ancient environments. Sedimentology is the scientific study of the classification, origin, and interpretation of sediments and sedimentary rocks. Stratigraphy is the science of studying the stratification (or layering) of sedimentary rocks. This course will communicate 1) the fundamental concepts behind sedimentology and stratigraphy, 2) the analysis and interpretation of modern and ancient environments of sediment desposition (rivers, lakes, oceans, deserts, glaciers), and 3) the applications of sedimentology and stratigraphy in environmental and economic pursuits.
