Abstract
The Geitafell Volcano, an extinct Tertiary central volcano, was active in the Icelandic rift zone between 5 and 6 Ma. Because of deep glacial erosion, the interior of the volcano is exposed from its flanks to the top of the extinct crustal magma chamber represented by several gabbro plutons. Here we present the results of a detailed study of the infrastructure of the Geitafell Volcano. The study includes measurements of the shape, size and fracture pattern of the extinct crustal magma chamber and its remarkably sharp contact with a dense swarm of inclined sheets for which the chamber acted...

Studies in Volcanology: The Legacy of George Walker

Professor George Patrick Leonard Walker was one of the fathers of modern quantitative volcanology and arguably the foremost volcanologist of the twentieth century. In his long career, George studied a wide spectrum of volcanological problems and in doing so influenced almost every branch of the field. This volume, which honours his memory and his contributions to the field of volcanology, contains a collection of papers inspired by, and building upon, many of the ideas previously developed by George. Many of the contributors either directly studied under and worked with George, or were profoundly influenced by his ideas. The topics broadly fall under the three themes of lava flows and effusion, explosive volcanism, and volcanoes and their infrastructure.
