The sand and gravel resources of the country around Newport-on-Tay, Fife region : description of 1:25,000 resource sheet NO 42 and parts of NO 32 and 52

The geological maps of the Institute of Geological Sciences, fifty-four boreholes and thirty-four shallow pits sunk for the Industrial Minerals Assessment Unit, together with data from eight other boreholes and the inspection of sand and gravel workings, form the basis of the assessment of sand and gravel resources in the Newport-on-Tay area, Fife 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 :250 00 map is divided into five resource blocks, four of which are assessed statistically and contain between 5.2 and 19.2 km2 of potentially workable sand and gravel. For the fifth resource block inferred assessments are offered for 3.6 km2 of mineral. The geology of the deposits is described and the mineral-bearing area, the mean thickness of overburden and mineral, and the mean grading are stated. Detailed borehole data are given. The geology and the outlines of the resource blocks, the position of boreholes and shallow pits used in the assessment are shown on the accompanying map.
