The sand and gravel resources of the country around Lymington and Beaulieu, Hampshire : description of parts of 1:25,000 sheets SU 20, 30 and 40, and SZ 29, 39 and 49

The geological maps of the Institute of Geological
Sciences, pre-existing borehole information, and 135
boreholes drilled for the Industrial Minerals Assessment
Unit form the basis of the assessment of the sand and
gravel resources of the country around Lymington and
Beaulieu, Hampshire.
All the deposits in the district that might be potentially
workable for sand and gravel have been investigated
and a simple statistical method has been 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 (printed as two overlapping sheets,
western and eastern) is divided into five resource blocks,
containing between 8.8 and 45.0 km2 of sand and gravel.
For each block the geology of the deposits is described,
and the mineral-bearing area, the mean thickness of
overburden and mineral and the mean gradings are
stated. Detailed borehole data are also given. The
geology, the position of the boreholes and the outlines of
the resource blocks are shown on the accompanying map.
