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 |
| Reason for describing collection: | paleoecologic analysis |
