The Elastic Behavior of Plagioclase Feldspar at High Pressure
Feldspars are one of the archetypical families of framework silicates. They not only comprise around 60% volumetrically of the Earth's crust, but are among some of the most structurally complicated minerals. Investigation into the structural behavior of various intermediate plagioclases at pressure …

Raman Spectroscopy and Synchrotron X-ray Diffraction Study of Lunar and Terrestrial Plagioclase Feldspar at High-Pressure and High-Temperature Conditions
Plagioclase feldspar is one of the abundant minerals on the surface of the Earth, the Moon and Mars, and is also commonly found in meteorites. This dissertation seeks to better understand the phase changes in plagioclase when subjected to meteorite impact and fundamental information about impact …

Deciphering the Signature of Magma Mixing: Examples from the Castle Creek Eruptive Period, Mount St. Helens, Washington
… and compositional imaging integrated with feldspar crystal chemistry data collected by electron microprobe. Petrographic and quantitative petrographic analyses were performed on 5 samples of Castle Creek basalt. MELTS closed-system fractional crystallization simulations were also executed …

Pattern formation in geochemical systems.
… investigated on a model of oscillatory zoning in plagioclase feldspar. It is shown that environmental noise can lead to pattern formation such as oscillatory zoning, even when no deterministic periodic solutions exist. Coherence resonance close to the Hopf bifurcation is observed. Oscillatory …

Methane adsorption into sandstones and its role in gas recovery from depleted reservoirs
… mineral components of sandstones (i.e. Quartz, Plagioclase, feldspar and clays), with methane (CH4), the effect of pressure and the interaction between water/brine and methane (CH4) gas in a competitive sorption environment for sandstones and their constituents. The first series of tests were …
