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.
