Muddy sandstone

The laminated muddy sandstone records low-energy fair-weather-wave deposition and subordinate storm-wave deposition. The Skolithos ichnofacies indicates a littoral to sublittoral environment. A shoreface environment between mean low tide level and fair-weather-wave base is interpreted for the association. 4.4.
