Geology at The Cliffs of Moher. The Cliffs form part of the Burren and Cliffs of Moher Geopark which was awarded membership of the UNESCO in 2011. Quarrying of the flagstone that occurs along the Cliffs of Moher and in their vicinity was a substantial industry in the 19th & 20th century.
Cliffs of Moher Geology The rocks that make up the Cliffs of Moher were formed over 300 million years ago during the Upper Carboniferous period. Bands of Namurian sandstone, siltstone and shale are exposed in a spectacular fashion and here one can study an example of a sedimentary basin normally only visible under the sea.
Geology alive! The Burren is not a barren and boring museum of stones, monuments and scientific curiosities. Quite the contrary, it is a living place teeming with nature’s bounty: ordinary and exotic rocks, plants, animals, insects and birds.
The cliffs take their name from an old promontory fort called Mothar or Moher, which once stood on Hag's Head, the southernmost point of the cliffed coast, now the site of Moher Tower. The writer Thomas Johnson Westropp referred to it in 1905 as Moher Uí Ruis or Moher Uí Ruidhin.
The Geological Society and partner organisations are celebrating the unique geo-heritage of the UK and Ireland with a list of 100 Great Geosites, featuring some of the most diverse and beautiful geology in the world.
The Cliffs of Moher located on the rugged west coast of Ireland have been carved out of the landscape over the course of millennia by the raging Atlantic ocean grinding away at the sandstone , siltstone and shale that dominate this part of the country .
At the Cliffs of Moher Visitor Experience you can learn about the formation of these famous cliffs; why they are of such international importance in terms of natural and geological heritage; and why the cliffs are a Special Protection Area. At the Cliffs of Moher, you can learn about the cliffs either indoors in the Atlantic Edge exhibition, or outdoors on the cliffs themselves.
History & Geology of the Cliffs of Moher. The area where the cliffs are today was the mouth of a large river years ago. 320 million years ago to be more specific. As a result of floods, sand and mud were washed here to become the compressed rocks as we know today. To become the Cliffs of Moher.
