Geological memoirs, Brief Sheet Explanations and Sheet Descriptions for each of the 1:50 000 series (and the earlier one-inch series) geological map sheets.
Memoirs contain detailed information on the structure, stratigraphy, and palaeontology, and many have sections on mineral resources, geohazards, groundwater and geophysics of the district.
Sheet Descriptions provide a similar level of information to that found in Memoirs, but with a more concise presentation.
Brief Sheet Explanations provide an summary of the geology of the district.
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.
Carboniferous rocks, deposited between about 350 and 310 million years ago, underlie the entire district. Most of the area is covered by a varying thickness of superficial deposits, and only in the northwest does the form of the ground bear any clear relation to the underlying bedrock structure. The Carboniferous succession, nearly 3000 m thick, was deposited in the Northumberland–Solway Basin. The Carboniferous sedimentary rocks represent the gradual infilling of the fault-controlled trough. Deposition in lagoonal coastal-flat environments in the early Carboniferous was followed by fluvial deposition and by the deposition of rhythmic units of limestone, mudstone, sandstone and coal on low-lying deltaic swamps with repeated shallow marine incursions. Extensional movements during early Permian times led to the emplacement of the Whin Dolerite Sill-swarm and of associated dykes of the Northern England Tholeiitic Dyke-swarm. A few basaltic dykes were intruded during the early Palaeogene. Superficial deposits of Quaternary age were deposited during the last, Devensian, glaciation. Postglacial and recent deposits include, alluvium, river terrace deposits and peat inland, with blown sand, tidal river, salt-marsh and marine deposits on the coast. [Booklet and Map Pack]

No 'modern' geological memoir is available for this district. This is a digital (‘POD’) reprint of an original out-of-print memoir which will provide an indication of the geology of the district. Print on demand (POD) publications - books, reports and maps - are printed digitally to order: this may include printing from digital scans of litho-printed original publications. …more…

The Lake District contains some of Britain's most outstanding scenery; it was recently nominated as a World Heritage Site. The spectacular landscape is the result of the area's geological history, evolution and erosion. The mountainous heart of the district is underpinned by Lower Palaeozoic rocks and it is those in the northern sector, comprising the Skiddaw Group, which are the subject of this memoir. This memoir, rather than covering one specific 1:50000 scale map, focuses on a stratigraphical unit covering several of these map sheets. …more…
