Quarries of the Mendip Hills
Encyclopedia
The Mendip Hills
are the most southerly Carboniferous Limestone
Upland in Britain
and are found in northern Somerset
.
They are composed of three major anticlinal structures, each with a core of older Devonian
sandstone
and Silurian
volcanic
rocks. The latter are quarried for use in road construction and as a concrete
aggregate.
In recent centuries the hills, like the Cotswolds
to the north, have been quarried for stone to build the cities of Bath and Bristol
, as well as smaller towns in Somerset. The quarries are major suppliers of road stone to southern England, between them producing around twelve million tonnes a year, employing over two thousand people with an annual turnover of £150m.
There are two main rock types on the Mendips: the Devonian
Sandstones visible around Black Down
and Downhead
and the Carboniferous Limestones
, which dominate the hills and surround the older rock formations.
A large proportion of the stone (about 5 million tonnes per year) is moved by rail company Mendip Rail
.
