E of the Geological Map of England and Wales, Illustrating the Geology of the Country Between Bradford and Skipton The rocks comprised within this area, excepting the Poet Tertiary beds, consist entirely of Carboniferous rocks, ranging from the Upper Limestone Shales to the upper beds of the Lower Coal Measures. The Lower Coal Measures occupy the southern portion, and form part of the most northerly extension of the Yorkshire Coal-field. Nearly the whole of the remaining part of this tract is occupied by the various members of the Millstone Grit Formation. The Upper Limestone Shales rise from beneath these beds in the north-west only, near Skipton. To the south and south-west the measures have a general north and south strike, but before entering our present district they begin to bend round, and finally range across the Country from Kildwick to Poole, with an east and west strike and a southerly dip. The superficial beds consists of the alluvial deposits in the valleys of the Rivers Aire and Wharfe; of Boulder Beds which are also mainly confined to the valleys; and of Esker Gravels, some of which occur at considerable elevations, and some are only found in the present alluvial plains of the main valleys. The geological structure of the district is complicated, and in many parts very Obscure, owing to the variable character of the measures, the number of the faults, the nature of the atmospheric denudation, and lastly, to the presence of Glacial Drift, which, in places, attains a thickness of from 100 to 200 feet.
