Lithology and environment
Primary lithology: floatstone
Secondary lithology: rudstone
Lithology description: stromatoporoid float‑/rud‑/boundstone (patch reef facies)
Environment:reef, buildup or bioherm
Geology comments: The middle to dark gray limestones consist of tabular and bulbous stromatoporoids. The dominant bulbous forms (ca. 50 % of the whole limestone) reach a diameter of up to 20 cm. Secondary are dendroid stromatoporoids, especially Stachyodes and Amphipora, tabulate corals (Thamnopora), and solitary Rugosa. Additional fossils are parathuramminids and ostracods. The matrix consists of coarse-grained detritus, slightly winnowed micrite, and peloids. Clay seams, grain penetration, and microstylolites are common, based on compaction and pressure solution
