Stratigraphy
Formation:Second Abden Shale
Local section:East Old Limekiln Local bed:73
Local order:bottom to top
Stratigraphic resolution:bed
Stratigraphy comments: Brigantian age was shown by Brindley and Spinner 1989, Proc. Yorkshire Geol. Soc. 47:215-231
Lithology and environment
Primary lithology: lithified silty,sandy "shale"
Lithology description: thin sections of the shale show it to consist predominantly of clay minerals with varying admixtures of sand and silt sized particles, normally quartz but with some chlorite and feldspar...interlaminations of fine sandy material in their more argillaceous basic substance.
Environment:transition zone/lower shoreface
Geology comments: Sediments were deposited in a gap between periods of volcanic activity, the series represents a transgression from tidal-flat to subtidal environment.
Taphonomy
Modes of preservation:body
Collection methods and comments
Collection methods:bulk,chemical,mechanical,peel or thin section,sieve,field collection
