The bioclastic limestones consist mainly of transported crinoidal
fragments, but brachiopods, corals, fusulinids, and even plant remains occur as well.
The stone is a light grey crinoidal
packstone that contains abundant coral macrofossils (Fig.
The Lower Visby marlstones, Upper Visby argillaceous limestones with marlstone intercalations, and the Hogklint crinoidal
(pelmatozoan) grainstones with reef-bodies are exposed in the Ireviken 3 section (Fig.
Tennessee "marble," a pink bryozoan/ crinoidal
limestone from the Holston Formation of eastern Tennessee is also evident in Erie Street Cemetery and Ridgeville Cemetery.
Carbonates of the studied wells are mainly of coarse-grained bioclastic, crinoidal
, brachiopod and stromatoporoid limestones intercalated with marls (Fig.
Overlying this sequence red-pinkish crinoidal
grain-stones are present, with intercalations in the upper part, of sandy limestones first and ferruginous oo-oncolitic limestone towards the top.
Its base falls within nodular limestone facies, overlain by a prominent unit of bedded crinoidal
grainstone (facies I, Fig.
