SUMMARY:Geology Workshop
DESCRIPTION:Classroom morning and hill-based afternoon\, looking at how the hills near Cribarth are linked to the Sea\, with Alan Bowring of Brecon Beacons National Park Authority. Possible content: \n\nCarboniferous Limestone – variety of units within it reflecting changing original marine depositional environments between 360 and 330 million years ago.\nSubsequent expansion of coastal deltas – the deposits now being known as the Twrch Sandstone and the Bishopston Mudstones of the Marros* Group (formerly the Basal Grit and Middle Shales of the Millstone Grit Series) *Marros is the coastal hamlet on the Pembs/Carms border where these rocks are magnificently displayed in the sea cliffs\, including Telpyn Point.\nFaulting and folding of the horizontal strata in the Variscan Orogeny due to ocean closure and mountain-building as witnessed along the Swansea/Cribarth Disturbance (which runs up from Swansea Bay).\nLegacy of the last Ice Age (including locally\, striations and polishing of sandstone surfaces\, glacial erratics) – water locked-up in ice-sheets caused global sea levels to fall as recorded\, for example\, on Gower Coast.\nDevelopment of karstic features – Britain’s deepest cave is opposite\, whilst Wales’ largest enclosed surface hollow in on Cribarth’s flanks. Plentiful shakeholes.\nIndustrial exploitation at Cribarth and nearby for limestone\, rottenstone and silica rock – exported via tramroads to Swansea canal and then down to the sea.\n\nAttendees must be either 2018 Full/Associate Individual Members or staff from 2018 Full/Associate Corporate Members or 2018 Supporters. Credentials will be checked on booking. \nAttendees will need to come with everything they need in order to feed and support themselves on the hill.
