Along-strike variation of structural style: Mansourabad Anticline in the Dezful Embayment, SW Iran

open access: yesResults in Earth Sciences
Understanding the governing factors that influence structural style and fault-related folding mechanisms is crucial in the Dezful Embayment, an area of ∼ 60,000 km2 which accounts for most of oil production from Iran.

Aging in magma rheology

open access: yesScientific Reports, 2022
AbstractAging, change in property depending on the elapsed time from preparation, is known to affect the rheological behavior of various materials. Therefore, whether magma ages must be examined to characterize potentially widespread volcanic phenomena related to the transition from rest to flow.

Exsolved volatiles in magma reservoirs

open access: yesJournal of Volcanology and Geothermal Research, 2018
We review our understanding of the exsolved volatile phase co-existing with magmas during pre-eruptive storage at the pressures and temperatures corresponding to crustal magma reservoirs.

Magma Plumbing Systems: A Geophysical Perspective

open access: yesJournal of Petrology, 2018
Over the last few decades, significant advances in using geophysical techniques to image the structure of magma plumbing systems have enabled the identification of zones of melt accumulation, crystal mush development, and magma migration.

Modelling of Magma Density and Viscocity Changes and Their Influences towards the Characteristic of Kelud Volcano Eruption

open access: yesIndonesian Journal on Geoscience, 2014
DOI: 10.17014/ijog.v6i4.129The effusive eruption of Kelud Volcano in 2007 was different from the previous ones, which in general were more explosive. Among others, density and viscosity are factors that determine the type of eruption.

Structural and Geochemical Interactions Between Magma and Sedimentary Host Rock: The Hovedøya Case, Oslo Rift, Norway

open access: yesGeochemistry, Geophysics, Geosystems, 2020
Two end‐member conceptual models are used to describe deformation of the Earth's crust induced by magma intrusion. “Mode I” fracturing assumes tensile or opening‐mode, elastic deformation, while “Mode II” fracturing assumes plastic shear‐mode deformation

Thick crust, hydrous magmas, and the paradox of voluminous cold magmatism

open access: yesVolcanica, 2021
Andesites are refined and “cold” magmas compared to their basaltic parents, yet large volumes of andesites are generated at continental arcs. We show that large andesitic plutons are favored when arc crust attains a thickness of ~60 km while mafic ...

On the mechanism of interaction between strong earthquakes and volcanism in subduction zones

open access: yesВестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле, 2022
The relationship between strong earthquakes and powerful volcanism in subduction zones are discussed. It is shown that abnormally strong earthquakes or a group of strong earthquakes and powerful volcanic events or volcanic activation of large areas can ...

Compositional Evolution of Polygenetic Fissure Volcanic Systems: Insights From the Latest Eruptions at Craters of the Moon Volcanic Field

open access: yesGeochemistry, Geophysics, Geosystems, 2023
The Craters of the Moon (COM) Volcanic Field in Idaho is the largest mostly Holocene lava field in the conterminous U.S. and the site of the most recent volcanism in the Yellowstone‐Snake River Plain province.

NATO i Zapadni Balkan u uvjetima novih sigurnosnih izazova

open access: yesMeđunarodne Studije, 2014
U skladu sa zaključcima donesenim na NATO-ovom samitu u Walesu, posebno s onim kako će NATO ostati „temeljem naše kolektivne obrane“, zemlje Zapadnog Balkana svjesne su važnosti pripadanja transatlantskom sigurnosnom okruženju, vođenom od strane NATO-a ...
