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"
