Goodrington Quarry and Road CuttingDesignations: CGS/RIGS Exposure of Middle Devonian (Givetian) Limestone. The site shows a valuable range of geological features. GCR block / key theme: Marine Devonian Associated SSSI: Not applicable Geological / geomorphological features: "MiddleDevonian (Givetian) limestone. Quarry area: Partly dolomitised, light-grey limestone with slickensided fault-plane surfaces, calcite crystals and stromatoporoids. Road cutting east side: Limestone beds, mainly thickly bedded and dolomitised, interbedded with micritic limestone. Stromatoporoids, corals and other fossils occur. The general dip is about 20° N, with very open, upright folds, at the southern end. Possible low-angle fault/thrust along bedding plane. Permian sandstone-filled fissures occur. Road cutting west side: Detailed examination difficult because of inaccessibility. Possible faults and Permian sandstone-filled fissures visible. The succession as a whole is considered to be a recumbent anticline." Reasons for registration as a CGS / RIGS sites: "The site, which is generally readily accessible to all interest groups, shows a valuable range of geological features which have been previously documented. There is considerable potential for future development as a valuable educational resource." |
