(b) Close-up view of massive conglomerate (Gm). Subrounded to rounded blade-shaped clasts exhibiting a(t)b(i) imbrication and clast-supported fabrics. (c) Cross-bedding (dashed lines) of planar cross-stratified conglomerate or gravelly sandstone (Gp/gSp). (d) Close-up view of the horizontally stratified sandstone (Sh). (e) Poorly sorted massive sandstone (Sm). (f) A gradual contact between the underlying ripple cross-laminated sandstone (Sr, dashed lines) and the overlying gray mudstone (Mg).
