Hartcliff Rocks Quarry (grid reference ST534662) is a 1.6 hectare (3.9 acre) Site of Special Scientific Interest (SSSI) near Felton, Somerset notified in 1991
The site provides exposures of Triassic Dolomitic Conglomerate unconformably overlying Carboniferous Limestone. Both rock types have undergone extensive replacement by siliceous iron oxides. The exposures and spoil heaps clearly demonstrate how the iron mineralisation is preferentially hosted by the more porous and permeable conglomerate. The iron ores, which are principally goethite and haematite, are also concentrated along the plane of the unconformity. Disseminated pink barite is also present in the iron-rich horizons, while calcite-barite veins and neptunian dykes can be clearly seen to cut across the iron mineralisation.[1]
