Sedimentary Petrology is the branch of geology that focuses on the study of sedimentary rocks and the processes that form them. It examines the composition, texture, and structure of these rocks, which are formed from the accumulation of sediments over time. These sediments can originate from various sources, including weathered materials from igneous and metamorphic rocks, as well as organic matter. The field also investigates the environments in which sediments are deposited, such as rivers, lakes, and oceans. By understanding these processes, sedimentary petrology helps geologists interpret Earth's history and the conditions that existed in different geological periods.
