| | == Introduction (From memoir) == |
| | |
| | [[File:P222330.jpg|thumbnail|Crag Lough and Highfield Crags, Roman Wall. ]] |
| | The Bellingham district includes much of the Roman Wall country, the Northumbrian lakes, North Tynedale and Redesdale—all areas of outstanding, unspoilt beauty. They are underlain by Carboniferous rocks, 1600 m thick which were laid down around 300 million years ago. In the south and east, 'Yoredale'; limestones, sandstones and shales with the intrusive dolerite of the Whin Sill form scarp and dip-slope features, but in the forested areas to the north and west thick boulder clay of Pleistocene age mantles most of the solid rock and forms its own distinctive drumlin topography. |
| | This memoir is the first comprehensive published account of the geology of the district. After an introductory chapter, the stratigraphy of the Carboniferous rocks is described in detail, with comprehensive correlation diagrams of sections and boreholes together with complementary palaeontological identifications. |
| | |
| | Accounts of the igneous rocks and structure of the region are followed by chapters on the Pleistocene and economic geology. Appendices list boreholes, shafts, measured sections and geological photographs and conclude with a comprehensive bibliography. |

| | Reference to the geology of the district can be found in many early works but the first systematic study was the primary six-inch geological survey by Hugh Miller Jnr., and D. Burns between 1875 and 1878. The solid edition of their one-inch map was published in 1881 followed by the drift edition in 1883. This map was not accompanied by a detailed geological succession nor were any major lithological subdivisions of the Carboniferous shown. A descriptive memoir written by Miller was not published. Small areas on the eastern and western edges of the district were resurveyed by G. A. Burnett (1932–35) and J. B. W. Day, D. H. Land and D. A. C. Mills (1954–58) respectively. |
| | This memoir is the first comprehensive description of the geology of the district (Figure 3), though a number of generalised descriptions have appeared in works which deal with wider regions (e.g. Lebour, 1889; Garwood, 1910; Smith, 1912; Hickling and others, 1931; Taylor and others, 1971). In addition, important contributions to knowledge of the Carboniferous rocks of the district include those by Tate (1867a), Lebour (1873, 1875a, b), Johnson (1959), Fowler (1966) and Frost (1969). Igneous rocks have been studied by Tate (1867a, b, 1870). Topley and Lebour (1877), Teall (1884a, b), Heslop and Smythe (1910), Weyman (1910), Holmes and Harwood (1928, 1929), Smythe (1930), Randall (1959a, b), and Ineson (1972). Mineral deposits have been described by Wilson and others (1922), Smith (1923) and Dunham (1948); and the drift deposits and glacial retreat phenomena by Dwerryhouse (1902) and Smythe (1908, 1912). |
| | Memoirs describing adjacent areas include those by Miller (1887), Clough (1889), Trotter and Hollingworth (1932), Fowler (1936) and Day (1970). |
