The limestone and dolomite resources of the country around Settle and Malham, North Yorkshire with notes on the hard rock resources of the Horton-in-Ribblesdale area : description of parts of 1:50,000 geological sheets 50 and 60

Information obtained from 10 cored boreholes and from minor sections, together with information from the records and geological maps of the Institute of Geological Sciences form the basis of the assessment of limestone resources in the Settle and Malham area, North Yorkshire. The petrology, mineralogy, chemistry and mechanical properties of the limestones have been investigated and the limestones have been classified on the basis of their calcium carbonate content. The accompanying map shows the distribution of the recognised categories of limestone at surface. Horizontal sections constructed from borehole data and from knowledge of the regional geology, indicate categories likely to be encountered at depth. Limestone purity is stratigraphically controlled and most of the boundaries between categories coincide with geological boundaries. The geology, the carbonate resources and the chemical and mechanical characters of each division are described. Detailed information is presented within the outline borehole logs appended. A brief description of the hard-rock sandstone and gritstone resources of the Horton-in-Ribblesdale inlier is included.
