Largy Quarry

The area is of special scientific interest because of its important geology, which is found at an outcrop in a quarry on the north east side of Largy hill. The rocks exposed are of Carboniferous age, some 320 million years old. The outcrop consists of interbedded sandstone, mudstone and conglomerates from the Ballyreagh Conglomerate Formation of the Kilskeery Group.

The rocks here date from the Carboniferous period of Earth history and are some 320 million years old.
They originated as sand, mud, pebbles and cobbles that built up in an area of land that was sinking at this time.
Pink to purple coloured sandstone is the most common rock found at the site, but it also contains fine grained mudstones and more coarse rocks, known as conglomerates.
These conglomerates are made up of pebbles or cobbles of other bits of rock, held together by sand or mud.
