The following descriptive texts are from the preface and
tourist guide which introduce the set of county geological
maps.

Preface:-
|
|
In constructing THE GEOLOGICAL ATLAS OF GREAT BRITAIN, an
endeavour has been made to combine convenience and
portability of form, with clearness and accuracy of
information. The Geographical portion of the Maps has been
drawn from the most reliable sources, including the Ordnance
Surveys; and the railways have been inserted to the period
of publication.
|
|
The great interest now taken in Geological science, has led
to the belief that the representation in such a work of the
Geological features of the several Counties and Districts
would prove of interest and utility, both to Geologists and
the public in general, and in order to ensure that the
utmost accuracy in laying down this information, the
following authorities have been consulted:-
|
|
The Maps of the Geological Survey of Great Britain
|
|
Greenough's fine Map issued by the Geological Society
|
|
The Maps of Phillips, Murchison, Knipe, Ramsay, and Forbes
|
|
The Works of Sir Charles Lyell, Professors Phillips, Ansted,
&c.

|
Mr. Prestwich on 'The Strata around London.'
|
|
Professor Forbes and Mr. Bristow on 'The Isle of Wight.'
|

The Editor's acknowledgements are also due to Professor
MORRIS, F.G.S., for his valuable suggestions and kind
assistance.

|
There is an essay on the
|
|
GEOLOGICAL STRUCTURE OF GREAT BRITAIN.
|
|
in which are comments about the several counties,
including:-
|
|
CUMBERLAND. The south-western coast and a large portion of
the north of this county is occupied by new red sandstone,
which forms also the fertile vale of Eden, on the east of
which is a high range of limestone mountains connected with
the Pennine chain The central portion of the county is
occupied by a group of mountains furrowed by deep and narrow
valleys. This cluster of mountains is for the most part
composed of silurian rocks of a slaty texture, with gneiss,
granite, and trappean rocks. This district is well known for
its picturesque scenery; and for the beauty of its numerous
lakes and waterfalls. The slate rocks are succeeded on the
north, north-east, and north-west, by mountain limestone,
beyond which, on the north-west, is the Whitehaven
coal-field. The minerals include iron, coal, lead, plumbago,
copper, silver, and limestone. Area 1,001273 acres.

LANCASHIRE. ... Furness is occupied partly by the
last-mentioned rock [carboniferous limestone], but chiefly
by silurian slate rocks. ...
|
|
...
|
|
WESTMORELAND. The most mountainous county of England, the
surface being almost entirely occupied by the mountains of
the Lake group. Slate rocks of the upper and lower silurian
series cover the greater part of the county, the rest of
which is occupied by carboniferous limestone and new red
sandstone. The soil is fertile in some of the lower vales,
especially in the fine vale of Kendal; but by far the
greater part of the surface is occupied as pasturage. Area
485,432 acres.
|
|
There are descriptions of various minerals and products
which might refer to the Lake counties, but not in any great
amount or detail. The tourist guide section has the 'usual'
information.
