Bøger af Agust Gudmundsson

Complete overview of Iceland's geology Main focus is on the relation to Mid-Ocean Ridges

This is the first book describing the glorious geology of IcelandΓÇÖs Golden Circle and four additional excursions:(1) the beautiful valleys and mountains of the Hvalfj├╢rdur, (2) the unique landscape and geothermal fields of the Hengill Volcano, (3) the explosion craters, volcanic fissures, and lava fields of the Reykjanes Peninsula, and (4) the volcanoes (Hekla, Eyjafjallaj├╢kull, Katla), waterfalls, sandur plains, and rock columns of South Iceland. The Golden Circle offers a unique opportunity to observe and understand many of our planetΓÇÖs forces in action. These forces move the EarthΓÇÖs tectonic plates, rupture the crust, and generate earthquakes, volcanic eruptions, channels for rivers and waterfalls, and heat sources for hot springs and geyers. The Golden Circle includes the famous rifting and earthquake fracture sites at Thingvellir, the hot springs of the Geysir area, the waterfall of Gullfoss, and the Kerid volcanic crater. As the book is primarily intended for people with no background in geosciences, no geological knowledge is assumed and technical terms are avoided as far as possible (those used are explained in a glossary). With more than 240 illustrations ΓÇô mostly photographs ΓÇô explaining geological structures and processes, it is also a useful resource for geoscientists.
