Which mountain range in Ireland was formed during Armorican folding?

The Galtee Mountains are indeed associated with Armorican folding, which occurred during the Late Paleozoic to Early Mesozoic eras, particularly around 300 million years ago. This geological process involved the collision of tectonic plates that led to significant folding and uplifting of the Earth's crust. The Galtees were primarily formed from sedimentary rocks, which were subjected to intense pressure and deformation during this period, resulting in the rugged topography characteristic of the range today.

In contrast, the other mountain ranges, such as the Mournes, Wicklow Mountains, and Slieve Blooms, have different geological histories. The Mourne Mountains are associated with more recent volcanic activity, and the Wicklow Mountains and Slieve Blooms primarily feature older granite formations, formed during an earlier geological period known as the Caledonian orogeny. Each range reflects distinct geological processes, making the Galtees the clear example of Armorican folding in Ireland.
