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.
The highest point in Iceland is HvannadalshnÃºkur in the ÃrÃ¦fajÃ¶kull glacier in Southeast Iceland, reaching a height of 2,110 m (6,950 feet). Prior to human settlement in the 9th century, trees covered up to 40 percent of the island. Today, however, there are only small areas of the original birch forests left.
