SOME NOTES ON THE YORKSHIRE COALFIELD AND ITS EASTWARDLY 
EXTENSION. BY PROF. ARNOLD LUPTON, F.G.S., M.I.C.E. 
{Read November 7th, 1894.) 
It is impossible to attempt more than an outline sketch of two 
or three salient features of the geology of the Yorkshire Coalfield, 
and any description must be something like a magazine story, " to be 
continued in our next." It may be completed sometime in the next 
century when the eastern boundary of the Coalfield has been ex- 
plored. In this respect the Yorkshire Coalfield differs from some 
others in this country to which the boundaries are completely traced, 
for instance, the Irish Coalfields are fully exposed. The boundaries 
of the Scotch and Northumberland Coalfields are known, except that 
they dip under the sea. The same remark applies to the Durham 
Coalfield, except the southern corner, which is covered by newer 
formations. The great Coalfield of Glamorgan and Monmouthshire 
has its boundaries well-defined, and the same may be said of the 
small Coalfield of the Forest of Dean. The Coalfields, however, of 
Somersetshire, South Gloucestershire, Staffordshire, Warwickshire, 
Leicestershire, Cheshire, Denbighshire, Shropshire, South West Lan- 
cashire and Cumberland are each unexplored on one side at least, 
and the newly-discovered Coalfield at Dover has not yet been seen 
by the eye of man in any part. It is therefore evident that the next 
century will provide plenty of work for those who explore our Coal- 
fields, but of all the storehouses of fuel there is none more likely to 
be vigorously explored than that great Coalfield which stretches from 
the latitude of Leeds, on the north, to the neighbourhood of Not- 
tingham, on the south. 
At a period before the geological maps of Yorkshire were pub- 
lished, the writer had occasion to make a geological examination of 
this Coalfield, and to prepare plans and sections for the use of the 
Royal Coal Commission, and in the year 1879 he contributed a paper 
to this Society on some of the features of this Coalfield. The writer 
has prepared a plan and sections to illustrate these notes.
