Identifying Sedimentary Rocks -- Earth Rocks!
Channel: Earth Rocks!
Date: 2014-06-26

For an introductory college-level physical geology class: a review of how to classify and identify a sedimentary rock. Includes a discussion of the textures and compositions of sedimentary rocks including chemical, bioclastic, and detrital clastic. Covers chert, flint, limestone, breccia, conglomerate, sandstones, mudstone, shale, coquina, calcarenite, chalk, and diatomite.

**ERROR IN VIDEO: The image that shows the Mammoth Hot Springs in Yellowstone should be labeled as travertine (calcite). Typically hot spring precipitates in volcanic regions are made primarily of silica. The Mammoth Hot Springs are uniquely calcareous because there's limestone layers under the terraces that are dissolving to create the ions that later precipitate as calcite (travertine) on the surface.
