Lithology and environment
Primary lithology: | grainstone | ||
Secondary lithology: | argillaceous lime mudstone | ||
Includes fossils? | Y | ||
Lithology description: "Lasiocrinus occur in interbedded 'ribbon limestone' facies; typically found on bedding planes of thin (2-4 cm) lamintaed calcisiltite beds interbedded with fine-grained argillaceous lime mudstone and shale layers" | |||
Environment: | lagoonal/restricted shallow subtidal | Tectonic setting: | foreland basin |
Geology comments: "The Manlius has bee interpreted as peritidal to lagoonal. Desiccation cracks,, birdseye (fenestral) fabric; cryptalgal laminites and intraclast conglomerates...portions upper intertidal to supratidal...Ribbon limestones interpretd as storm silt and fine sand layers washed into a 'lagoonal' environment: the latter situated between carbonate tidal flats and offshore shoal settings...A nearshore, somewhat unstable silty environment, is indicated; generally low energy background conditions interrupted by frequent storm events...BA 2"
