Description

PEOP. C. LAPWOETH ON THE GIEVAX SUCCESSION.
657
Between these beds and the southern margin of the overlapping
strata of the Lower Carboniferous to the north, beds of flagstone,
varying from a foot to a few inches in thickness, and separated by
seams of striped blue and grey shales, are seen at several spots in the
Lady Burn

they are occasionally fossiliferous, affording
Cyrtoceras, sp. j Monograptus vomerinus, Kick.
Orthoceras subundulatuin, Portl. \ Fleiningii, Salt.
It is doubtful if any of these beds actually belong to the Bargany
group of the area last described, though they greatly remind us of
the strata of that group in their general features. They clearly
belong both physically and geologically, however, to the same
general series as the Bargany beds, possibly following them in the
natural order of succession.

4. Knoclcgardner and Straiton (fig. 30). — The flaggy strata of the
three subzones of the Blair beds range from this point eastward to
the village of Straiton, a distance of at least 3± miles, running
strictly parallel with the Bargany fault to the southward. In the
course of a small stream descending the north slope of Benan Hill, a
mile south-west of Straiton, the cold olive-green flags of Drumyork are
again seen in contact with the Old Red Sandstone. The more finely
laminated strata of Blair Farm are exposed in quarries at the farm-
steading of Knockgardner, where they are crowded with Beyrichia
Kloedeni, M'Coy, and yield a few scattered examples of characteristic
Blair fossils, Pterinea pleuroptera, Conr., Orthonota truncata, Conr.,
&c, and indeterminate species of Cyrtograptus and Monograptus.
The same beds are seen further east in the banks of the Cawin
Burn. Of the most northerly or highest (?) zone of the Blair beds,
only a short section is seen in the streams running down the peaty
region north of Shaw's

Knowes.

Public domain

This work is in the public domain in its country of origin and other countries and areas where the copyright term is the author's life plus 70 years or fewer.

This tag is designed for use where there may be a need to assert that any enhancements (eg brightness, contrast, colour-matching, sharpening) are in themselves insufficiently creative to generate a new copyright. It can be used where it is unknown whether any enhancements have been made, as well as when the enhancements are clear but insufficient. For known raw unenhanced scans you can use an appropriate {{PD-old}} tag instead. For usage, see Commons:When to use the PD-scan tag.
