Scenic Red Rock Canyon hides amid the scruffy slopes of the Santa Monica Mountains, not far from the San Fernando Valley communities of Woodland Hills and Calabasas. Slabs of cavernous sandstone and ...

Scientists at the Tucson-based Planetary Science Institute (PSI) have found further evidence for the large role that water has likely played in shaping the Martian landscape. Their results, which will ...

Sedimentology explores the origin, transport, deposition and diagenetic alterations of the materials that compose sediments and sedimentary rocks. Stratigraphy investigates how those types of rocks ...

Marine barite extracted from deep-sea sediment cores, seen here in a scanning electron microscope image, provides a record of variations in ocean chemistry over geologic time. (Image by Adina Paytan) ...

Some comments and discussion in a recent post about stratigraphy motivated me to finish this post about the future of sedimentary geology, which I started a few months ago but never finished. The fact ...

High-latitude evaporites-late Proterozoic through Early Permian-are widespread in Canada and Eurasia. Their distribution patterns show that they precipitated from marine waters entering the continents ...

A search for ancient deposits of sandy material expected at continental margins has come up empty. This prominent geological gap hints at poorly understood, powerful, global-scale erosion processes, ...
