Sedimentology is the scientific discipline within the Earth sciences that investigates the origin, transport, deposition, and post-depositional modification of sedimentary particles and the rocks they form. It focuses on physical, chemical, and biological processes governing sediment production (weathering and erosion), transport mechanisms (e.g., fluvial, aeolian, glacial, and marine), depositional environments, and early diagenetic transformations. Sedimentologists analyze grain size, composition, sedimentary structures, and stratification patterns to infer process dynamics and environmental conditions, providing quantitative constraints for basin analysis, paleoenvironmental reconstruction, reservoir characterization, and stratigraphic modeling.
Wild animals are not just inhabitants of the natural world. Many also act as natural landscape engineers, reshaping Earth's surface as they burrow, feed, and build shelters that move soil and sediment across ecosystems. From ...

Because oxygen-bearing sulfate minerals trap and preserve signals from Earth's atmosphere, scientists closely study how they form. Sulfates are stable over billions of years, so their oxygen isotopes are seen as a time capsule, ...

Over the past 8,000 years, Utah's Great Salt Lake has been sensitive to changes in climate and water inflow. Now, new sediment isotope data indicate that human activity over the past 200 years has pushed the lake into a biogeochemical ...
