Geochemical and petrological investigation into the magmatic system at Soufrière Hills Volcano, Montserrat.
… at depth. The processes of mass transfer and flux of material involved in the interaction between mafic and silicic magmas are crucial for understanding eruption dynamics. Detailed textural, petrological and geochemical analyses coupled with field observations are used to define a …

Drivers of Variation in the Eruptive and Magmatic Processes of a Persistently Active Volcano, Yasur, Vanuatu
… were observed to indicate changes in magma and volatile flux across the whole volcano. Other ~5-day fluctuations at individual vent zones reflected changes in magma and degassing percolation within each upper conduit branch. An overall decline in the strength of activity during the observation …

Applications of Elastic Modeling, Thermobarometry, and Thermal History Modeling to (Ultra)high-Pressure Metamorphic Rocks
… and geochemical processes (i.e. orogenesis, volatile flux into the mantle, etc.), it is important to understand the depth-temperature conditions of mineral reactions during the subduction-exhumation metamorphic cycle. (Ultra)high-pressure ((U)HP) metamorphic rocks, such as blueschists and …

The Effects of Contact Metamorphism by Diabase Intrusion on the Carbon and Sulfur Bearing Phases in the Siltstones of the Culpeper Basin
… the release of carbon and sulfur bearing volatiles and has been proposed as one of mechanisms that drove these mass extinctions. In this study I examine a dike of the Central Atlantic Magmatic Province and its interaction with adjacent sedimentary rocks in the Culpeper Basin of Virginia. …
