uses (British Geological Survey, 2009). The UK is more or less self-sufficient in meeting its silica sand needs. In 2012, silica sand production in the UK was 3.9 million tonnes. Of this total output, 87% was produced in England, 11% in Scotland, 4% in Wales and none in Northern Ireland (Office for National Statistics, 2014).
UK silica sand resources • The UK is nearly self-sufficient in silica sand • 40 quarries produce 4Mt of silica sand (2010 figures*) • Sandstone (weakly cemented) e.g. Carboniferous Passage Fm, central Scotland (glass) • Glacial sand e.g. Pleistocene Chelford Sand F m, Cheshire (flat glass) • Near shore marine/ coastal (dune / beach) sand
