The Global ETD Search service is a free service for researchers
to find electronic theses and dissertations. This service is
provided by the
Networked Digital Library of Theses and Dissertations.
Our metadata is collected from universities around the world. If you manage a university/consortium/country archive and want to be added, details can be found on the NDLTD website.

Basaltic volcanism, volcanoes and volcanic rocks of marine and lacustrine environmentsJones, John Gilbert January 1968 (has links)
Intraglacial basaltic volcanoes near Laugarvatn, south-west Iceland, range from simple pillow lava piles to tuyas - volcanoes of tablemountain form in which a superstructure combining a carapace of sheet lava on a pedestal of breccia envelops a tuff-mantled pillow lava pile. The pillow lava piles are inferred to be the product of effusion of lava into glacial meltwater, and the tuff cappings which most exhibit record a later phase of explosive emergence from the meltwater pond. The sheet lava and flow-foot breccia of the tuyas are believed to record an ultimate phase of lava effusion in air, following earlier phases of aqueous effusion and explosive emergence, in which flows advanced outwards into encircling meltwater on deltas of breccia formed at their fronts. The little that is known of the morphology and constitution of marine basaltic volcanoes suggests that they are basically similar to the Laugarvatn volcanoes and that concepts derived from the study of the latter have general application. Examination of the structural characteristics of Icelandic and Welsh pillow lavas suggests a mode of formation and propagation akin to the digital advance of pahoehoe: and a vesicularity study indicates the potential importance of pillow lavas as depth indicators. Review of the literature suggests that explosive activity, induced by extraneous water, is characteristic of eruption of basalt lava from a wet vent in shallow water and in air. Observations of the immersion of basalt lava are reviewed, and the significance of structural records of immersion is indicated. A re-examination of the type 'peperites' suggests that they are the product, not of brecciation of lava intruded into wet sediment as is currently accepted, but of explosive projection of basaltic ejecta into steadily accumulating lime mud.
