Volcanoes amongst Ireland
While I researched volcanic activity in Ireland this week, I came up a little short of what I thought I might find. From what I have found, all volcanic activity that was once known around 200 million years ago, is now extinct. Some of the most popular extinct volcanoes include, Slieve Gullion in Co Armagh, Lambay Island in Dublin, Loch Na Fooey in Co Galway, and Croghan Hill in Co Offaly. Most of the volcanoes were formed from molten rock beneath oceans that are still in existence today. All though these volcanoes are not in existence today, they are still a part of Irelands history and a reminder of what used to be in the Emerald Isle.

The volcanism in Ireland is "gone but not forgotten". Ireland and my country, Iceland, share many similarities. The main difference is that they are in different stages of life. Iceland is very young, and still forming. It's piece of crust is still over the mantle features that cause it to grow. Ireland is much older, and it's crust has already moved away from the areas of volcanism. One thing that is constant though, is that both of them are doomed. Iceland too will move away from it's hot spots, and no more new land will replace that which is eroded away. By this time Ireland will likely be nothing but a memory, if there are still humans around to remember it. To me this perception of time is one of the most awe inspiring things about the study of geology.
ReplyDeleteIt is interesting that you found out about Ireland what I found out about Romania, and namely the fact that all volcanic activity is extinct, although there is geological research about Romania that points to possibilities that volcanic phenomena are still possible. I assume there wasn't any research pointing to that about Ireland. Ireland is located in the middle of the Eurasian plate, as you pointed out in your earlier posts, so, I would expect there would still be some potential for volcanic activity. I found Brendan's comment so intriguing and it made think about a documentary about plate tectonics that I saw on Discovery which showed how the evolution over time of tectonic plates and their future evolution as well; very, very, very interesting; I am in awe about what the future will look like for the planet, according to computer simulations and geologic calculations...I wish I would live at least a few million years so as to be able to witness this...Quite amazing!
