Cornell researchers have unearthed precise, microscopic clues to where magma is stored, offering scientists – and government officials in populated areas – a way to better assess the risk of volcanic ...
Volcanologists are gaining a better understanding of what's going on inside the magma reservoir that lies below New Zealand's Mount Tarawera volcano. They're finding a colder, more solid place than th...
Although volcanic eruptions are often quite hazardous, scientists have been unable to pinpoint the processes leading up to major eruptions – and one important limitation has been a lack of knowledge a...
Volcanologists are gaining a new understanding of what’s going on inside the magma reservoir that lies below an active volcano, and they’re finding a colder, more solid place than previously thought, ...
The rare but spectacular eruptions of supervolcanoes can cause massive destruction and affect climate patterns on a global scale for decades – and a new study has found that these sites also may exper...
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...
A new analysis of the topography of the central Andes shows the uplifting of the Earth's second highest continental plateau was driven in part by a huge zone of melted rock in the crust, known as a ma...
This paper presents a security bound in the standard security model for the Magma cipher CTR encryption mode and the 獵ryptoPro Key Meshing?(CPKM) re-keying method that was previously used with the GOS...
We show that a Magma implementation of Joux’s L[1/4 + o(1)] algorithm can be used to compute discrete logarithms in the 1303- bit finite field F36·137 and the 1551-bit finite field F36·163 with very...
Months of warning signs from Mauna Loa, on Hawaii’s Big Island, prompted the U.S. Geological Survey to recently start releasing weekly updates on activity at the world’s largest active volca...
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 ...
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...
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 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...
Fe in magma - An overview     iron  silicate melt  redox conditions       2015/9/10
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...
