Economic Value of Rocks
• Recreation; Hill walking, Climbing• Tourism; Burren• Decorative Pieces; Fireplaces, Headstones,
Worktops• Construction Materials; Gravel, Limestone• Metals; Lead, Zinc, Gold• Energy Source; Coal, Oil, Gas, Geothermal

Quarrying
• Important Resources• Construction Industry• Granite, Limestone and Marble are the most
common rocks quarried in Ireland

What is Quarrying?
• Removal of Rocks from the Earths Surface• 400 active quarries in Ireland• In recent year with the improved
developments in infrastructure in Ireland, there has been an increased demand for quarried materials

Chapter 5: The Rock Cycle• Methods of quarryingI. Plug and feather
drilling holes split the rock extracting large pieces, e.g. floor
coveringII. Explosive
extracting large and small pieces of rock
III. Channelling machinery cuts large slices of rock metamorphic rock such as marble
