Dr. Bruce Railsback of the University of Georgia's Department of Geology provides this online Atlas of Speleothem Microfabrics. Here he presents petrographic or electron microscope images of most known microfabrics found in stalagmites, stalactites, flowstones, and other chemically precipitated cave deposits. Notes Railsback, "Variation in the mineralogy, shape, size, clarity, orientation, and...

"The International Association of Sedimentologists (IAS) was founded in 1952 with the goal to promote the study of sedimentology and the interchange of research, particularly where international cooperation is desirable." The website provides visitors with the association's monthly newsletter, which discusses conferences, recent studies, workshops, and more. Students and educators can learn about...

This paper deals with the Proterozoic Yellowjacket Formation in the Lemhi Range, Idaho. The stratigraphy, sedimentology, and structural history are described.

The Society for Sedimentary Geology (SEPM) "is dedicated to the dissemination of scientific information on sedimentology, stratigraphy, paleontology, environmental sciences, marine geology, hydrogeology, and many additional related specialties." The website presents the latest and upcoming meetings, workshops, and other events. Individuals can find newsletters of the many SEPM sections and...

The USGS Bedform Sedimentology Site offers materials that are companions to the book: Cross-Bedding, Bedforms, and Paleocurrents, by D. M. Rubin of the USGS Pacific Science Center. Visitors can read an online version of the book, read about bedform initiation, view QuickTime and MPEG movies of bedforms and cross-bedding, download bedform simulation software, and find out how to identify...

The sedimentology group at the University of Minnesota presents its research in earthscape processes at this website. Visitors can find out about the goals, results, and publications of three main research areas: experimental stratigraphy and landscape evolution, theoretical sedimentology and stratigraphy, and river dynamics. The site offers downloads for many of the group's publications. Visitors...
