The Geology Group
The group welcomes new members
Many of the group's meetings are on-site, at varied dates and times according to the availability of access (e.g. tides, site opening times).
For information contact Caz Donovan the group's coordinator.
Reports from the Group:
On Tuesday 18th June 9 of the geology group went to explore Berry Head quarry. This massive quarry is now a nature reserve and is worth exploring not only for the features in the limestone but also the wild flowers that Terry happily pointed out for us.
Some of the features in the limestone are the caves, the fossils including the extensive stromatoporoid reefs (a type of sponge) and crinoids as well as the distinctive Nepturnian dykes – cracks in the limestone infilled with calcite crystals and Permian red sandstone. We also tried to figure out the methods used for quarrying and spotted quite a few drill marks. The rain held off and we had a quick visit to the bird hide before lunch at the Fort cafe.
