Excerpt from The Geology of the Country North and East of Harrogate: Quarter Sheet 93 N. W. Of the Geological Survey A small area at the north-east corner of the map, where the ground begins to rise again in that direction, is occupied by the shaly sandstones of the Middle Lias, the soft marls and shales of the Keuper and Lower Lias being entirely hidden by an immense thickness of alluvial deposits. The country under notice is almost entirely agricultural, there being no mines or manufactures of any extent.

The resurvey of the Harrogate district carried out between 1973 and 1978 was intended primarily to assess its economic mineral wealth, notably sand and gravel. It also yielded information on the Permian limestone resources, which are a valuable source of aggregate for the construction industry, and produced important scientific information, such as the marked thickness changes in the Carboniferous sequence along the margin between the Askrigg Block and the Craven Basin. A modern account of the Quaternary glaciation of the area is also included and potential sources of geological hazard are identified.
