Map dated March 1st. 1824
Copies known dated 1831

Stratigraphy
Red Sandstone & Marl of the Vale of Eden. Detached Limestones.
Red Sandstone of St Bees
Limestone sunk through for Coal at Preston How
30 Coal field of Whitehaven, Workington &c. Some Coal worked below the level of the Sea.
Shale Grit with some Coal above the Limestone
31 Metalliferous Limestone underlaying the Coalfield. Red Iron ore in this Rock near Cleator.
[In northeast]
Lime. Coal. Coarse Grit. Shale & Grit. The same Alternations of Shale, Grit rocks, Limestone & thin Coals as in the adjacent part of Northumberland which are much obscured by Peat and alluvial pebbles.
[In east]
Coal. Shale & Grit. Coarse Grit Alternations above the Limestone. Shale Grit, thin Limestone and bad Coal seams.
31 Metalliferous Limestone in many beds alternating with Grit and Shale, very productive of Lead Ores. Many fine waterfalls over Limestone beds.

33 Dark soft Schist of Skiddaw, Saddleback and Grisdale Fells in which the Lakes Derwent, Bassenthwaite, Buttermire & Crummock are situate      It contains Lead, Copper Blende and other Ores.
Mottled Red argillaceous rock near Keswick
33 Grey slate of Buttermire and Borrowdale, associated with Hornstone, amygdaloid & argillaceous Porphyry Characterized by bold towering Crags. Produces Copper and Lead Ore.

GEOLOGICAL MAP OF DURHAM, by W.SMITH, Mineral Surveyor

First published in Part VI of A New Geological Atlas of England and Wales…1824 with Cumberland, Northumberland and Westmoreland.
Map dated March 1st. 1824
Copies known dated 1831

Stratigraphy
Basalt or Great Whin Sill in lofty ranges from Caldron Snout, down the south side of the Tees. At High force it rests on dark Limestone.
28 Red Sand rock along the Banks of the Tees. The sulphurous water of Middleton found by boring in this Rock.
28 Red & Bluish Clay with alluvial matter extending to the summits of drainage above the Magnesian Limestone
29 Yellow or Magnesian Limestone / Yellow or Magnesian Limestone often dusty, sometimes brecciated, and at Building hill, in imitative concretions presents lofty cliffs against the Sea. Sunk through for Coal at Hetton lehole and Ferryhill.
30 Coalmeasures consisting of Shale & Grit rocks with numerous seams of Coal the prime Coal for London is obtained from a tract two to four miles wide ranging across the Tyne & Wear southeastward to and under the Magnesian Limestone. Around Durham dusty bad Coal. At West Pits and Thornly Pithouses in the lowest part of the Series, excellent Coal. Muscle-band Ironstone at Prudhoe __ The principal Grit rocks are marked by various shades of brown. The situations of the principal Collieries are marked by a dark Alluvial matter abounds in the eastern part of this Coalfield.
Millstone Grit
Alternations between the Limestone and Millstone Grit, consisting of Shale grit thin Coal seams and a thin Lime.
Metalliferous Limestone beds causing many waterfalls on the branch streams. Lead mines abundant in Wear dale and Tees dale.
