Common sedimentary structures
WebSep 9, 2024 · Sedimentary rocks often show distinctive patterns that are unrelated to their type of rock, yet reflect events or conditions during deposition and are called sedimentary structures. These patterns in the rocks can be very informative to geologists attempting to reconstruct the environment in which a sedimentary rock was formed.
