Geological Survey Ten Mile Map

---

	map type:- Geological Survey 1948 Ten Inch
	Geological map, 2 sheets, The Geological Survey Ten Mile Map, Geological Map of Scotland and the North of England, and Geological Map of England and Wales, scale about 10 miles to 1 inch, by the Geological Survey on outline maps by the Ordnance Survey, 1948. There are stratigraphical columns giving the colours, and letter codes, for the geological strata printed on each sheet. Beware: the colourings and codings are declared for Scotland and England north of 55Km N, and England south of 550Km N, an are different. This is awkward for the Lakes area. The whole map is printed on two sheets, Great Britain North and South. The Lakes area is divided, part on each sheet. The stratigraphical colouring does not change at the 550Km line, but notice that the letter codings are given in both systems.
