Lithology description: "The common lithology is a calcareous, predominantly siliciclastic mudstone with variable amounts of skeletal debris. In some areas, echinoderm or bryozoan packstones to grainstones and boundstones are dominant, usually extending laterally no more than a few meters. Irregular lumps of algal limestone...are often surrounded by rocks with the textures noted above..." | |||
Environment: | deep subtidal indet. | Tectonic setting: | cratonic basin |
Geology comments: "echinoderm attachment structures common...debris piles...trilobites seldom intact...echinoderm crowns very rare...The community most likely represents BA 4-5 deposited below normal wave base but subject to sporadic storm disturbance. The deep end of the spectrum is perhaps most likely, as other similar communities have rare ischaditids or other large green algae, but these have not been found here." |
