Geology of the Black Mountain, western Brecon Beacons
Saturday 4th July
Geraint Owen (Swansea University)
The Black Mountain (Mynydd Du) is the western part of the Brecon Beacons. It lies within the Fforest Fawr Geopark and the Brecon Beacons National Park and is traversed by the Beacons Way. The geology comprises gently southward-dipping Palaeozoic strata on the north side (“North Crop”) of the South Wales Coalfield, ranging in age from late Silurian to late Carboniferous. As befits its location within the National Park, the area is scenically attractive, with extensive views to the south over the industrialised South Wales Coalfield and to the north into rural mid Wales. Although outside the area of coal-bearing rocks, the area contains an important legacy of extractive industries and associated infrastructure.
Several sites will be visited and the ground conditions may be rough and wet underfoot in places. Bring warm, waterproof clothing and sturdy, waterproof footwear. Please bring a packed lunch. Safety helmets are advisable at one site.
Further details and suggested reading list are available on request from the Society.
21st April - Mine Water Temperatures in the South Wales Coalfield: A Potential Source of Low-Carbon Heating Energy
David Tucker (WDS Green Energy) & Gareth Farr (BGS)
Abandoned mine workings within the South Wales Coalfield are often flooded with groundwater that has the potential to be a major energy source for heat pumps.
Venue: Atkins, The Hub (Ground Floor), 500 Park Avenue, Aztec West, Almondsbury, Bristol, BS32 4RZ.
The spheres above represent the volume of erupted tephra for some of the most widely-known volcanic eruptions. Most people believe that Vesuvius in AD79, Mount St. Helens 1980, Mount Pinatubo 1991 were enormous but, as you can see, they were very small compared to ancient eruptions such as Wah Wah Springs, Toba, Yellowstone and Long Valley.
