Pembrokeshire has an outstanding range of geological features in a relatively compact area, making this an ideal location for your summer visit.
Ideal for interested amateurs, we will cover a fascinating range of scenery, interpreting a wide variety of igneous, sedimentary and metamorphic rocks, the way they were formed and what they tell us about the history of the area. We will look at the range of Palaeozoic rock sequences to see how the environment changed through the vastness of geological time.
We will see how Pembrokeshire’s rocks, and what they contain, can give us lots of information about conditions in the past including climate, water depth, distribution of land and sea, topography, and the latitude, plate tectonics and distribution of continents. We will also study evidence for the more recent development of the landscape; in particular the effect of the passage of ice sheets, with concurrent changes of sea level, in producing the distinctive, spectacular Pembrokeshire hills and coast.
Please note this is a level 2 walking course.

Provisional Course Programme
The field programme aims to cover all the main geological periods seen in Pembrokeshire. There will be a choice of the following field days depending on the weather and tide conditions and preferences of the group.
1. The Cambrian and Precambrian around St. David’s highlighting the building stones of the Cathedral, a spectacular pair of igneous bodies and the first fossil trilobites.
2. Ordovician volcanic rocks in North Pembrokeshire - pillow lavas, sills, and explosive volcanic rocks near Strumble Head and fossiliferous graptolitic slates at Abereiddi Bay.
3. Precambrian igneous rocks, and Coal Measures rocks and structures in the Broadhaven area.
4. The Preseli Hills for ‘bluestones’, megalithic tombs and deserted slate quarries, Ordovician turbidite sediments and folding at Poppit Sands and Llangranog.
5. Silurian volcanic rocks, sediments and Old Red Sandstone at Marloes Sands, the Wooltack Peninsula and St Ann’s Head
6. Spectacular carboniferous Limestone cliff scenery, fault lines and Permian gash breccias on a short Coast Path walk from the Green Bridge of Wales. The Old Red Sandstone at Freshwater East and Manorbier.
