Second Abden Shale, Level 24 (Carboniferous of the United Kingdom)

Where: Scotland, United Kingdom (56.1° N, 3.2° W: paleocoordinates 1.8° S, 2.5° E)

• small collection-level geographic resolution

When: Second Abden Shale Formation, Brigantian (336.0 - 330.9 Ma)

• Brigantian age was shown by Brindley and Spinner 1989, Proc. Yorkshire Geol. Soc. 47:215-231

• bed-level stratigraphic resolution

Environment/lithology: transition zone or lower shoreface; lithified, silty, sandy shale

• Sediments were deposited in a gap between periods of volcanic activity, the series represents a transgression from tidal-flat to subtidal environment.
• 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.

Collection methods: bulk, chemical, mechanical, peel or thin section, sieve,
