On the Volcanic and Geodynamic Evolution of the Shatsky Rise and the Louisville Seamount

Creator:

Heaton, Daniel E.

Abstract:

Large igneous provinces (LIPs) and intraplate seamounts reflect of anomalous mantle melting and illuminate interior processes of the Earth. These features are in all ocean basins and show the mantle’s evolution over time, then can provide information on plate tectonic processes, such as plate motion over time, spreading ridge formation,...

Timescales and tectonics of oceanic plateaus : long-term evolution of Ontong Java Nui and Rio Grande Rise

Creator:

Davidson, Peter C.

Abstract:

Oceanic plateaus are regions of overthickened oceanic crust and are often thought to form from the interaction of mantle plumes with oceanic lithosphere. These regions can cover vast areas of the ocean basins and represent a highly elevated magmatic flux relative to normal mid-ocean ridge spreading. Oceanic plateaus are considered...

Volatile mobility of trace metals in volcanic systems

Creator:

Loewen, Matthew W.

Abstract:

Semi-volatile trace metals like Li, Cu, Mo, Sn, In, and Pb have the potential to track mobility of a volatile phase in volcanic systems. In this dissertation four studies are presented that either directly investigate or are motivated by observations of trace metal behavior in volcanic systems. A common tool...

Investigating Timescales of Resurgence at Large Calderas: Post-74 ka Activity at Toba Caldera, Sumatra, Indonesia

Creator:

Mucek, Adonara E.

Abstract:

The Toba Caldera Complex is the youngest resurgent caldera in the last 100 kyrs, formed from four overlapping eruptions starting 1.2 Myrs ago. The last caldera-forming eruption, the Youngest Toba Tuff eruption, occurred ~74 kyrs ago, emitting 2800 km3 of ash and pumice into the atmosphere and forming the caldera...
