A type of igneous rock. Basalt is the most common rock type in the earth's crust and makes up most of the ocean floor.
Chemically, rocks in Iceland reflect their origin at a hot spot in the middle of the ocean. Another such hot spot-they are 25-30 in all-is Hawaii in the Pacific Ocean which is characterised by many of the same types of rock as Iceland. There is, however, one interesting exception:(dacite and rhyolite) are much more common in Iceland than in Hawaii, where such rocks are almost totally absent, and in fact Iceland is probably quite unique among oceanic islands in this respect.sked By.
