The Castleton Area, Derbyshire GA Guide

During the last 16 million years (up to recent times) igneous rocks with a variety of compositions have been extruded and then moved E or W of the rift valley which marks the central line of the Mid-Atlantic Ridge The ice sheets and their associated glaciers formed by the accumulation of snow over hundreds of years, occupy 11% of Iceland. The pressure on water trapped in geothermally heated cavities close to the land surface is occasionally relieved generating Geysers. The itineraries in the Guide provide a representative selection of sites of the above.

compiled by M.R.Dobson

The Aberystwyth Grits and Borth Mudstones (Silurian) are magnificently exposed in accessible cliffs along the coastline of Cardigan Bay and are world-famous as classic examples of turbidity current deposition. But the region is also known for the variety of its glacial landforms and modern sedimentary environments . Nineteen itineraries are described in detail, the first eight dealing with the variations in the turbidite fan succession between New Quay in th south and Harp Rock in the north. The rest cover the Dovey Estuary, the Quaternary and solid geology of Cardigan Bay and the Plynlimon area. A glossary is included.
