SANDSTONE - 'YORK' ETC
Sandstones are sedimentary rocks where small sand or grit particles have been coalesced with silicas, calcium and other deposits, sometimes iron bearing. Usually laid down in semi-separated beds, sandstones are often quarried by cleaving the stone free from the underbed.
Sandstones and associated gritstones are used for paving in public spaces, also for ashlar and masonry for buildings. Because they do not polish under footfall or traffic they have great longevity when used for paving.
