Chemical and textural equilibration of garnet during amphibolite-facies metamorphism: The influence of coupled dissolution-reprecipitation [PDF]
, 2017 Metamorphic equilibration requires chemical communication between minerals and may be inhibited through sluggish volume diffusion and or slow rates of dissolution in a fluid phase.

Intergranular diffusion rates from the analysis of garnet surfaces: implications for metamorphic equilibration [PDF]
, 2017 Novel approaches to garnet analysis have been used to assess rates of intergranular diffusion between different matrix phases and garnet porphyroblasts in a regionally metamorphosed staurolite-mica-schist from the Barrovian-type area in Scotland.

Recycling Argon through Metamorphic Reactions: the Record in Symplectites [PDF]
, 2018 The 40Ar/39Ar ages of metamorphic micas that crystallized at high temperatures are commonly interpreted as cooling ages, with grains considered to have lost 40Ar via thermally-driven diffusion into the grain boundary network.

Primary crustal melt compositions: Insights into the controls, mechanisms and timing of generation from kinetics experiments and melt inclusions [PDF]
, 2017 We explore the controls, mechanisms and timing of generation of primary melts and their compositions, and show that the novel studies of melt inclusions in migmatites can provide important insights into the processes of crustal anatexis of a particular ...

Participation in the U.S. Ellsworth Mountains operation of the 1979-1980 austral summer, Antarctica
Antarctic Record, 1981 Field activities in the Ellsworth Mountains in the 1979-1980 austral summer were supported from a temporary U.S. base camp. To study metamorphic petrology, the author mainly surveyed Marble Hills, Liberty Hills, Edison Hills, High Nunatak, and Wilson ...
