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.
