The Asbeck Quarry exposes a sequence of more
than 600 meters of reefal limestone.
There are six major facies sets: 
1. limestones with evidence of subaerial exposure (e.g., vadose cements, drying and contraction cracks), 2. laminites without macrofauna (but with
parathuramminid foraminifers and ostracods), 3.
micrites with few components and irregular
microbial fenestrae (“birdseyes” to Stromatactis”), 4. fossiliferous micrites, with various reef builders, gastropods, specialized brachiopods, parathuramminids, and ostracods, 5. sublagoonal limestone, mostly rich in dendroid stromatopores (Amphipora, Stachyodes), and 6. reef-core limestones (boundstones), with large stromatopores in growth position.


Mudstones to bioclastic wackestones with some
tabulate corals, rare colonial Rugosa, very rare
stromatoporid fragments, some crinoid debris,
ostracods, and some mollusk debris.
