    Release the crackin': The influence of brittle behavior on gas retention in crystal-rich magma

    Crystal-rich silicic lavas commonly erupt from hazardous lava dome-forming volcanoes, characterized by both effusive and explosive eruptions. Magma explosivity is inherently dependent on its ability to store p...

    Direct nanoscale observations of degassing-induced crystallisation in felsic magmas

    Water degassing plays a major role in magma transport and eruption by increasing liquidus temperatures, bubble and crystal volume fractions, and strongly affecting the viscosity of bulk magma. High spatial res...

    Thermal properties of carbonatite and anorthosite from the Superior Province, Ontario, and implications for non-magmatic local thermal effects of these intrusions

    Igneous intrusions are important to the thermomechanical evolution of continents because they inject heat into their relatively cold host rocks, and potentially change the distribution of radiogenic heat produ...

    Thermal diffusivity of rhyolitic glasses and melts: effects of temperature, crystals and dissolved water

    Thermal diffusivity (D) was measured using laser-flash analysis on pristine and remelted obsidian samples from Mono Craters, California. These high-silica rhyolites contain between 0.013 and 1.10 wt% H2O and 0 to...

    Rheology of arc dacite lavas: experimental determination at low strain rates

    Andesitic–dacitic volcanoes exhibit a large variety of eruption styles, including explosive eruptions, endogenous and exogenous dome growth, and kilometer-long lava flows. The rheology of these lavas can be in...

    The role of H2O in rapid emplacement and crystallization of granite pegmatites: resolving the paradox of large crystals in highly undercooled melts

    Granite pegmatite sheets in the continental crust are characterized by very large crystals. There has been a shift in viewing pegmatites as products of very slow cooling of granite melts to viewing them as pro...

    Transport properties of high albite crystals, near-endmember feldspar and pyroxene glasses, and their melts to high temperature

    Thermal diffusivity (D) was measured using laser-flash analysis (LFA) from oriented single-crystal albite and glasses near LiAlSi3O8, NaAlSi3O8, CaAl2Si2O8, LiAlSi2O6 and CaMgSi2O6 compositions. Viscosity measure...

    Temperature-dependent thermal diffusivity of the Earth’s crust and implications for magmatism

    The rate of heat transfer by conduction is the dominant factor that determines the thermal evolution of planetary crust and lithosphere. Most thermal models of the Earth's crust assume constant values for ther...

    The viscosity of hydrous dacitic liquids: implications for the rheology of evolving silicic magmas

    The viscosity of a series of six synthetic dacitic liquids, containing up to 5.04 wt% dissolved water, was measured above the glass transition range by parallel-plate viscometry. The temperature of the 1011 Pa s ...

    Transport properties of low-sanidine single-crystals, glasses and melts at high temperature

    Thermal diffusivity (D) was measured using laser-flash analysis from oriented single-crystal low-sanidine (K0.92Na0.08Al0.99Fe3+ 0.005Si2.95O8), and three glasses near KAlSi3O8. Viscosity ...
