Each year many hundreds, if not thousands, of Earth‐science students visit the coastline at Ogmore‐by‐Sea, mid‐Glamorgan. They study the excellent exposures of Lower Carboniferous Limestone, with their well‐preserved coral and other shelly faunas, together with the presumed late Triassic ‘breccias’* that rest unconformably on top. A study of the cements within the breccias may give an insight into syndepositional mineralization and the formation of sedimentary basins linked to the opening of the Atlantic in early Mesozoic times.
