Sb

Medium- to very coarse-grained/conglomeratic, structureless, bioturbated sandstone with reddish-yellowish-purplish colors. Granule and pebble size quartz and mud clasts occur dispersed in the sets

Sh

Medium- to very coarse-grained sandstone with parallel stratification forming cosets with 0.5 to 0.8 m in thickness. Planar crossbedding occasionally marked by quartz clasts at the base of sets

St

Coarse- to very coarse-grained sandstone, locally conglomeratic, with through cross-stratification forming cosets with 1.0 to 1.5 m in thickness and a fining-upward trend

Gm

Conglomerate with coarse-grained sandy matrix composed of rounded to angular pebbles of quartz and mud clasts with 0.5 to 20 cm in diameter

Gt

Conglomerate composed of angular pebbles of quartz 0.5 to 10 cm showing trough crossbedding and forming sets with 20 to 40 cm in thickness
