Sequence stratigraphy is a branch of geology that focuses on the analysis of sedimentary rocks and their relationships to past environmental and climatic conditions. It involves the study of sedimentary sequences, including the identification of depositional environments and the recognition of stratigraphic relationships between different rock units. Sequence stratigraphy can be used to reconstruct past sea-level changes, sedimentary basin development, and the evolution of sedimentary systems over time. This research area is important for understanding Earth's history and predicting future geological events.
