Electromagnetic expression of axial magma chambers
The electrical conductivity of sea floor materials is a strong function of porosity, pore geometry, fluid content, temperature and percentage of partial melt. These material properties are particularly volatile near the midocean ridge. Tracking electromagnetic eddy currents generated on the sea floor as they diffuse across the ridge can provide images ...

The Origin of Co-Magmatic Andesite Enclaves in the Rabor Miocene Pyroxene Andesites, SE Kerman, Iran: Insights from Textural and Mineralogical Composition [PDF]
The Miocene pyroxene andesite lava flows are exposed in southeastern edge of Urumieh Dokhtar Magmatic assemblage in Iran. The hypocrystalline andesite in parts contain conspicuous co-magmatic igneous enclaves which are dark grey and occur mostly as ...

Timescale of open-reservoir evolution beneath the south Cleft segment, Juan de Fuca ridge
International audienceLavas erupted at the southern end of the intermediate Juan de Fuca ridge (Cleft segment) are mostly cogenetic and their chemical diversity results from melt evolution in an open magma system.

The theoretical basis for textural indices of eruption dynamics: review and new conceptual models
The textural indices of eruption products (pumice, scoria and lavas), number density of crystals or bubbles, or characteristics of their size distributions, have been proposed to estimate dynamic properties such as magma ascent rates, on the basis of ...

Role of mechanical erosion in controlling the effusion rate of basaltic eruptions
In many basaltic eruptions, observations show that the effusion rate of magma has a typical dependence on time: the effusion rate curves show first a period of increasing and later a decreasing phase by a maximum value. We present a model to explain this

The shallow magma chamber of Stromboli Volcano (Italy)
In this work, we integrate artificial and natural seismic sources data to obtain high‐resolution images of the shallow inner structure of Stromboli Volcano. Overall, we used a total of 21,953 P readings from an active seismic experiment and an additional
