Stratigraphy
Stratigraphic resolution:group of beds
Stratigraphy comments: Upper part of member. 340 m thick overall.
Lithology and environment
Primary lithology:gray lithified siltstone
Secondary lithology:fine lithified silty sandstone
Lithology description: Alternating steel blue to gray hard siltstones and gray fine-grained silty sandstones (beds from a few centimeters to 10–30 cm) with thin (1–2 mm) lamination visible only at the weathered surface as alternating dark and lighter bands and with coarser alternation (0.3–1.0 cm) of gray siltstones, ferruginate at the weathering surface, and black shales. Hard siltstones and sandstones with stratal fracture form packets 1–2 m thick; packets of alternating siltstones and shales seem to be thinner (0.5 m ?).
Environment:coastal indet.
