Mee, Katy; Linley, Kathrine A.; Mankelow, Joseph M.; Shaw, Richard A.. 2011 Modelling the quality of sand and gravel resources in 3D. [Poster] In: Cities, catchments and coasts: applied geoscience for decision-making in London and the Thames Basin, London, UK, 13 May 2011. (Unpublished)
The construction industry is a critical sector of the UK economy and natural aggregates, such as crushed rock, sand and
gravel, are the most commonly used construction minerals. Demand for aggregates will continue into the future and
this demand will primarily be met by indigenous production. However, minerals can only be worked where they occur
and with increasing pressure on land use, it is important
that mineral resources are identified and appropriately
safeguarded. It is imperative that we understand how
these deposits are distributed not just on the surface but
also underground (Figure 1).
Whilst 2D mineral resource data is proving invaluable
in assisting planners, developers and industry in landuse
planning and decision-making, it does come with
limitations, such as being unable to depict the internal
variation in the quality of the deposit with depth or
provide an indication of the ratio of mineral to waste.
Such information is essential when assessing the
economic viability of extraction and, within BGS, 3D
modelling techniques are being used to address these
issues.
