Iceland can be divided into three zones based on the age of the basaltic rocks. Tertiary flood basalts make up most of the northwest quadrant of the island. This stack of lava flows is at least 3,000 m thick.celand formed by the coincidence of the spreading boundary of the North American and Eurasian plates and a hotspot or mantle plume â an upsurge of abnormally hot rock in the EarthÂ´s mantle.
Iceland is one of the most tectonically active countries on the world. This is a constructive plate boundary. As this new material is being forced to the Earthâs surface the surrounding plates are being pushed further apart. Creating new land, however, it does not create fertile soil in Iceland because the weather is too cold to weather the lava flows (unlike in tropical areas where new soils are soon formed).
