A review of Anisotropy of Magnetic Susceptibility analysis of Indian dykes: Implications on magma emplacement

The analysis of Anisotropy of Magnetic Susceptibility (AMS) is a powerful and rapid technique to examine the preferred orientations of mineral (magnetic) fabrics and can indicate the nature of a magma transport (vertical or lateral). The relationship between magnetic fabric and geometry of a dyke swarm enables us to understand magma emplacement processes. Depending on the mutual relationship of...

Oxygen isotope study of the Long Valley magma system, California: isotope thermometry and convection in large silicic magma bodies

Products of voluminous pyroclastic eruptions with eruptive draw-down of several kilometers provide a snap-shot view of batholith-scale magma chambers, and quench pre-eruptive isotopic fractionations (i.e., temperatures) between minerals. We report analyses of oxygen isotope ratio in individual quartz phenocrysts and concentrates of magnetite, pyroxene, and zircon from individual pumice clasts o...

How caldera collapse shapes the shallow emplacement and transfer of magma in active volcanoes

Calderas are topographic depressions formed by the collapse of a partly drained magma reservoir. At volcanic edifices with calderas, eruptive fissures can circumscribe the outer caldera rim, be oriented radially and/or align with the regional tectonic stress field. Constraining the mechanisms that govern this spatial arrangement is fundamental to understand the dynamics of shallow magma storage...

Lunar Volcanic Eruptions: Range of Eruption Styles and Implications for Magma Ascent and Emplacement

Introduction: A wide variety of morphologic features representing a range of eruption styles has been documented on the Moon [e.g., 1-2]. We have characterized the nature of numerous steep-sided domes, small shields, cones, dark halo craters of internal origin, dark mantle deposits, linear rille-related deposits, and sinuous rille-related deposits on the Moon using Clementine multis-pectral, Ap...

Eruptible magma.

For those who remember the classic disaster-docudrama Supervolcano (BBC-Discovery Channel 2005), the adjective “eruptible” is likely to ring a bell. Set in the near future and generally quite scientifically literate, the movie envisions volcanologists trying desperately to evaluate the near-term threat posed by the giant Yellowstone magmatic system. At the heart of their mission, and of the dra...
