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.
A new study led by the University of Southampton and research institutes in France has uncovered the mystery of how mini sand dunes form on beaches and in deserts.

In the 1970s, images from the NASA Mariner 9 orbiter revealed water-sculpted surfaces on Mars. This settled the once-controversial question of whether water ever rippled over the red planet.
