The Ancient Volcanoes of Great Britain, Volume 2 (of 2)

The volume surveys Britain's igneous history from Carboniferous through Permian to Tertiary times, presenting regional field studies, maps, and illustrations that document dykes, sills, volcanic necks, plateaux, lavas and fragmental deposits. It describes petrographic characters, structural relations, contact metamorphism, and the geometry and distribution of intrusive and extrusive bodies across England, Scotland, Ireland, the Isle of Man and adjacent islands. Comparative discussion links ancient features to modern volcanic processes, using volcanic vents, basalt plateaux and dyke systems to reconstruct eruptive styles, stratigraphic succession, and changing paleogeography while clarifying methods for estimating relative age and origin of the volcanic rocks.
