The limestone resources of the Craven Lowlands : description of part of 1:50,000 geological sheets 59, 60, 61, 67, 68 and 69

The study of borehole cores and samples from quarries and natural exposures, together with information from the records and geological maps of the Institute of Geological Sciences, forms the basis of the assessment of limestone resources in the Craven Lowlands. The limestones are classified on their calcium carbonate content, and the accompanying 1:50 000 resource map shows the distribution of the categories of limestone recognised at outcrop. Eleven resource blocks have been outlined and for each, the geology, the categories of limestones and the occurrences of other rocks are described. The results of investigations of chemical and mechanical properties are presented with outline borehole logs.
