American Sedimentological Society

The American Sedimentological Society (ASS) is a professional organization dedicated to the study of sedimentology—the science of sediments like sand, silt, and clay, and how they form, move, and stay layered over time. It brings together scientists, researchers, and students to share knowledge about Earth's surface processes, such as river or ocean sedimentation and ancient sedimentary rocks. The society promotes research, education, and collaboration in understanding Earth's sedimentary environment, contributing to fields like geology, environmental science, and natural resource management.
