Groundwater geologists must know about stratified rocks to locate aquifers and determine patterns of groundwater flow. Many problems in engineering geology and geologic hazards require some understanding of the stratigraphy of the rocks important to a particular project. Environmental geology problems also require knowledge of sedimentology and stratigraphy. Other areas of geologic research rely upon knowledge of stratified rocks. Sedimentary rocks are the primary sources geologists have about the history of the earth. Information on past life comes solely from sedimentary rocks. In the study of plate tectonics, stratigraphic data are important to reconstructing past plate positions and configurations. Knowledge of past climates can be interpreted from sedimentologic data and paleontologic data Understanding mass extinctions, such as at the K/T boundary, also depends on knowledge of stratified rocks. The goal of this course is to provide you with a fundamental understanding of (1) the processes by which sediments are deposited and sedimentary rocks are created and (2) the stratigraphic principles that we use to interpret layered rock successions. 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, stratigraphic principles. We are going to start at the smallest scale, that of a grain, and then work our way into bigger and
