Local section:Scottish Midland Valley Local bed:Unit 3
Local order:bottom to top

Lithology and environment
Primary lithology:lenticular,"cross stratification",deformed bedding,grading,tuffaceous,green "siliciclastic"
Includes fossils?Y
Lithology description: Consequently, horizons are of very limited lateral extent (often lens-shaped in transverse section: Fig. 10b)...Soft sediment deformation features...Greenish tuffs vary greatly in texture from fine sandstones to coarse agglomerates, and consist of diagenetically-altered basalt fragments in a complex, largely secondary matrix. Both upward-fining and upward-coarsening graded horizons evident.
Environment:"channel" Tectonic setting:back-arc basin
Geology comments: Consists of an over-steepened channel, numerous erosion surfaces represented by small-scale unconformities and disconformities. Strongly indurated.
