(Carboniferous Shale) - 2002
The Upper Carboniferous
beds at Radstock are the Upper Coal Measures. Within
the Radstock formation, coal seams frequently occur
at the lower end of this formation, for this reason
Radstock became a very popular location for coal mines
in the Avon area. However due to the inconsistency's
of these seams and the fact that they were usually
quite thin, the quarries shut down and moved out into
other areas. At the disused quarry, the top of the
Radstock formation has been removed and the coal seams
at the lower end, the fossilferious beds are those
of the Farrington & Barren Red Formations which
contains the hard rocks at the base seen occasionally
scattered around the quarry. Bands of Red measures
occur within the shale at the top of this formation
containing very poorly preserved and corroded plant
fauna.
