The lunar magma ocean volatile signature recorded in chlorine-rich glasses in KREEP basalts 15382 and 15386
chlorine fluorine Moon water glass
2017/4/10
The last liquids of the lunar magma ocean, known as urKREEP, should be highly enriched in volatiles, such as water,
fluorine, and chlorine. We find chlorine-rich glasses in two pristine KREEP basalts...
The 3550 year BP-1944 A.D.magma-plumbing system of Somma-Vesuvius: constraints on its behaviour and present state through a review of Sr-Nd isotope data
Somma-Vesuvius magma chamber crustal contamination
2015/9/15
Vesuvius, dominating the densely-populated Neapolitan area, is one of the most dangerous volcanoes in the World. Its destructive power derives from energetic subplinian and plinian eruptions, such as ...
The relationship between volatile content and the eruptive style of basaltic magma: the Etna case
volatile content eruptive style
2015/9/14
Fourier Transform Infrared (FT-IR) spectroscopic analyses of melt inclusions from four explosive eruptions of Etna (Italy) were conducted to determine pre-eruptive dissolved volatile concentrations. T...
A possible model for initiationof ULF oscillation in magma
ULF oscillations magma volcano electromagnetic emission
2015/9/14
During the period just prior to an earthquake, an electomagnetic emission develops over seismic zones. In this paper, a model of excitation of magnetic fields over zones of volcanic activity is propos...
Noble gas solubility in silicate melts:a review of experimentation and theory, and implications regarding magma degassing processes
noble gases solubility degassing silicate melts
2015/9/10
Noble gas solubility in silicate melts and glasses has gained a crucial role in Earth Sciences investigations and
in the studies of non-crystalline materials on a micro to a macro-scale. Due to their...
The strong influence of physical conditions during magma formation on Fe equilibria offers a large variety of
possibilities to deduce these conditions from Fe-bearing phases and phase assemblages fou...
It was a bit like making a CT scan of a patient’s head and finding he had very little brain or making a PET scan of a dead fish and seeing hot spots of oxygen consumption. Scientists making seismic im...
Evidence of magma activation beneath the Harrat Lunayyir basaltic field (Saudi Arabia) from attenuation tomography
Seismic attenuation model and the earth's crust Cenozoic basalt the earthquake happened S wave seismograms damping structure
2015/1/6
We present a seismic attenuation model for the crust beneath the Cenozoic basaltic field of Harrat Lunayyir (western Saudi Arabia), where a strong seismic swarm occurred in 2009. The tomography invers...
Mantle-derived arc related mafic enclaves and host orthogneiss from the Shyok Suture Zone of NE Ladakh, India: An evidence of magma-mixing
mafic enclaves (ME) orthogneiss (OG) magma-mixing Shyok Suture Zone NE Ladakh
2017/4/11
The Shyok valley in the northern Ladakh is a linear NW-SE trending suture zone (Shyok Suture Zone) and separates
two distinct terranes, the southern continental margin of Eurasian Plate to north, and...
Petrology of some oceanic island basalts: PRIMELT2.XLS software for primary magma calculation
mantle plumes oceanic island basalts mantle potential temperature primary magma
2014/4/8
PRIMELT2.XLS software is introduced for calculating primary magma composition and mantle
potential temperature (TP) from an observed lava composition. It is an upgrade over a previous version in
tha...
Influence of Non-Newtonian rheology on magma degassing
Non-Newtonian rheology magma degassing Soft Condensed Matter
2011/8/4
Abstract: Many volcanoes exhibit temporal changes in their degassing process, from rapid gas puffing to lava fountaining and long-lasting quiescent passive degassing periods. This range of behaviors h...
Viscous heating in fluids with temperature-dependent viscosity:implications for magma flows
Viscous heating in fluids temperature-dependent viscosity magma flows
2009/11/12
Viscous heating plays an important role in the dynamics of fluids with strongly temperature-dependent viscosity because of the coupling between the energy and momentum equations. The heat generated by...
