Abstract/Summary

The geological maps of the Institute of Geological Sciences, fifty-one boreholes and twenty-three shallow pits sunk fort he Industrial Minerals Assessment Unit, together with data from twelve other boreholes and the inspection of sand and gravel workings, form the basis of the assessment of sand and gravel resources in the area around Callander and Dunblane, Central Region. All deposits in the area which might be potentially workable for sand and gravel have been investigated and a simple statistical method used to estimate the volume. The reliability of the volume estimates is given at the symmetrical 95 per cent probability level. The 1:25 000 map is divided into four resource blocks, which contain between 2.6 and 9.6 km2 of potentially workable sand and gravel as distinct fromm potentially workable morainic drift. The geology of the deposits is described and the mineral-bearing area, the mean thickness of overburden and mineral, and the mean grading of the various types of deposit are stated. Detailed borehole and section data are given. The geology and the outlines of the resource blocks, the position of the boreholes, shallow pits and sections used in the assessment are shown on the accompanying map.
