Infiltration Metasomatism of Cumulates by Intrusive Magma Replenishment: the Wavy Horizon, Isle of Rum, Scotland [PDF]
The Eastern Layered Intrusion of the Rum Layered Suite comprises paired peridotite and allivalite (troctolite and gabbro)layers forming 16 macro-rhythmic units.

The Origin of Co-Magmatic Andesite Enclaves in the Rabor Miocene Pyroxene Andesites, SE Kerman, Iran: Insights from Textural and Mineralogical Composition [PDF]
Journal of Sciences, Islamic Republic of Iran, 2012 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 ...

Geophysical Research Letters, 2016 The Wudalianchi Volcano Field (WDF) is a typical intraplate volcano in northeast China with generation mechanism not yet well understood. As its last eruption was around 300 years ago, the present risk for volcano eruption is of particular public ...

, 2015 Layered mafic intrusions (LMI) are large, stratified igneous bodies of great economic significance. The constitutive crustal magma chamber(s) supplied by mantle-derived magma pulses exhibit complex mineralogical and chemical layering.

The theoretical basis for textural indices of eruption dynamics: review and new conceptual models
Earth, Planets and SpaceThe 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
Geophysical Research Letters, 2016 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)
Geophysical Research Letters, 2017 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

Geochemistry, Geophysics, GeosystemsOwing to their abundance and relative availability on Earth's seafloor, mid‐ocean ridge basalts (MORBs) have a well‐defined chemical element budget, reflected by the low standard deviation associated with typical normal MORB (N‐MORB) composition. However,
