Stratigraphy
Formation:Waldron Shale
Stratigraphic resolution:group of beds
Stratigraphy comments: "Middle Wenlockian. In Tenn. the equiv. portion of the Waldron Member, Wayne Formation, is mostly in the Kockelella amsdeni Zone." Unit 3 (from bottom) of Frest (1977), which is one of five units within the basal 1 m of the Waldron.
Lithology and environment
Primary lithology: calcareous mudstone
Secondary lithology: wackestone
Includes fossils?Y
Lithology description: "The dominant lithology is a marlstone (calcareous mudstone) with less than 20% megafossil clasts (most of the matrix is fine siliciclastics, but more rarely wackestone to packstone also occur)."
Environment:deep subtidal shelf Tectonic setting:cratonic basin
Geology comments: "The [wackestone and packstone] are interpreted as winnowed storm debris layers by Feldman (1989)...Echinoderms seldom complete...most cups and calices spar-filled...branching root systems and holdfasts common...Fossils generally concentrated within several m of masses of algal-fistuliporoid Lst...This is most likely an inner BA 4 community..."
