Geologists don’t only focus on a single rock outcrop to interpret the paleoenvironment of a region; they look at many outcrops so they can see how an environment changes across a region. The corporate headquarters are located in Houston. Siltstone is deposited in a similar environment with shale, but is usually located near the old delta, lake or sea shore, where calm currents cause less particle suspension. Siltstone is generally formed adjacent to sandstone deposits – ie close to beaches and delta edges where sand is deposited.
