Sedimentology and Stratigraphy

The study of sediments such as silt, clay and sand, and the processes that shape their formation is referred to as sedimentology. Some of these processes are weathering, erosion, deposition, transport and diagenesis. Studies of sedimentary rocks and structures are fundamental to the reconstruction of past environments and understanding of the Earth's geologic history. The principles of superposition, original horizontality, lateral continuity and cross-cutting relationships are vital to the...
