Up-section, the succession is characterized by a meter-scale intercalation comprising dolomitic marlstone, dolomite with lenses of pebbles, (sandy/intraclastic) limestone, and reddish sandstone. Locally, lamination, current ripples, trough cross-bedding, and weak bioturbation including Ophiomorpha and small Thalassinoides have been observed.

Our terminology includes lithoclasts, intraclasts, pellets and peloids, and coated grains. Lithoclasts Lithoclasts (see illustration above) are irregular fragments of limestones that were eroded and transported within or from outside of the basin of deposition. They are sometimes called extraclasts or detrital grains (right figure).
