41 Buckingham district - Sheet Explanation for sheet E219 plus 1:50 000 (S&D) map

This pack contains a Sheet Explanation for the district and the complementary 1:50 000 scale Bedrock Geology and Superficial Deposits map (folded). Sheet Explanations provide a brief description and interpretation of the geology of the relevant map sheet area. The A5 Sheet Explanation booklet and the map are supplied in a transparent wallet. While it is possible to buy the map and Sheet Explanation separately, buying them together as map pack saves you £3. The Buckingham district is an important development area, within easy reach of London and the Midlands conurbations. It includes the expanding towns of Bicester, Buckingham, Brackley and part of Milton Keynes. The district is divisible into four parts, each with a recognisably distinct topography. The western part, underlain by Jurassic strata, has much of the character of the Cotswolds with narrow valleys cutting through open 'uplands'. The south-central part is a clay vale of low relief, excavated into mudstones such as the Oxford Clay. The south-eastern part is dominated by flat-topped hlls capped by Portland, Purbeck and Lower Cretaceous strata and the north-eastern part is a plateau underlain by thick glacial drift deposits, dissected by the Great Ouse river system. Information on the area's geology and applied geology, including hydrogeology, engineering geology and mineral resources is also provided in this publication.

43 Builth Wells district - Sheet Explanation for sheet E196

Sheet Explanations provide a brief description and interpretation of the geology of the relevant BGS 1:50 000 scale map sheet area. More detailed geological information for the same area is available via the Sheet Descriptions. Sheet Explanations are printed A5 booklets and are available either singly, or as a pack together with the relevant 1:50 000 scale map, where this map is available. The Builth Wells district covers the south-eastern margin of the Cambrian Mountains and the escarpment of Mynydd Eppynt in Powys, in Wales. Parts of Ceredigion and Carmarthenshire are also covered. The geology of this area has a long history of research, and contributions to the early understanding of the district have been made by Murchison, De la Beche, and Lapworth. This new Sheet Explanation provides an up-to-date interpretation based on new mapping and includes a comprehensive study of the Quaternary deposits and contains a section on the applied geology.

51 Cardigan and Dinas Island district - Sheet Explanation for sheet E193

Sheet Explanations provide a brief description and interpretation of the geology of the relevant BGS 1:50 000 scale map sheet area. More detailed geological information for the same area is available via the Sheet Descriptions. Sheet Explanations are printed A5 booklets and are available either singly, or as a pack together with the relevant 1:50 000 scale map, where this map is available. Much of the area described in this Sheet Explanation lies within the Pembrokeshire National Park. Spectacular coastal cliffs between Dinas Head and Cemaes Head reach heights of 160m above sea level and inland, deep valleys and gorges incise into the smooth, rolling landscape. The bedrock of the district is deformed Ordovician deep water sedimentary rocks faulted and metamorphosed around 400 million years ago.

59 Chichester & Bognor district - Sheet Explanation for sheet E317 [Book]

Sheet Explanations provide a brief description and interpretation of the geology of the relevant BGS 1:50 000 scale map sheet area. More detailed geological information for the same area is available via the Sheet Descriptions. Sheet Explanations are printed A5 booklets and are available either singly, or as a pack together with the relevant 1:50 000 scale map, where this map is available. The Chichester and Bognor district lies on the south-western edge of the Weald, stretching from the South Downs to the coast at Selsey Bill. Geologically, it lies within the Wessex basin, on the southern limb of the Wealden Anticlinorium. The oldest formations known to be present at depth are of Devonian and Carboniferous age, but the main period of basin development and sedimentary deposition occurred during the Mesozoic, and a thick sequence of Jurassic strata underlies the Cretaceous rocks that outcrop at the surface. Sedimentary deposition was eventually terminated in mid-Cainozoic times, when extensive earth movements resulted in the formation of a series of large en échelon folds, each marking major faults at depth. This brief account describes the geology of the district. The oldest exposed strata are part of the Lower Cretaceous Wealden 'Group'. Passing south, these are successively overlain by the Lower Greensand Group, Gault and Upper Greensand formations and the Upper Cretaceous Chalk Group. Cainozoic (Palaeogene) strata underlie the broad coastal plain, and include the Reading Formation, London Clay Formation and the Bracklesham Group. [Book]
