The Normanshill in Geostin
Glen is mainly quarreled with
zones of marble, triolite & blue
free shale that have no mica.
Chadwick says he collected them
in the shale some 10 to 20 ft.
of Normanshill shale. In the
Europe place, in the Broom street
quarry, Chadwick thinks them to
be often phyllite.
The Normanshill is fine
in Cathedrals and at least
200' and maybe twice as thick.
An anticline here.
