Petrology of some oceanic island basalts: PRIMELT2.XLS software for primary magma calculation [PDF]

open access: yes, 2008
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 that it includes garnet peridotite melting and it detects ...

Dynamics and energetics of bubble growth in magmas: Analytical formulation and numerical modeling [PDF]

open access: yes, 1998
We have developed a model of diffusive and decompressive growth of a bubble in a finite region of melt which accounts for the energetics of volatile degassing and melt deformation as well as the interactions between magmatic system parameters such as ...

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.

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.

Modeling Viscosity of Volcanic Melts With Artificial Neural Networks

open access: yesGeochemistry, Geophysics, Geosystems, 2022
Viscosity is of great importance in governing the dynamics of volcanoes, including their eruptive style. The viscosity of a volcanic melt is dominated by temperature and chemical composition, both oxides and water content.

Nonlinear phenomena in fluids with temperature-dependent viscosity: an hysteresis model for magma flow in conduits

open access: yes, 2002
Magma viscosity is strongly temperature-dependent. When hot magma flows in a conduit, heat is lost through the walls and the temperature decreases along the flow causing a viscosity increase. For particular values of the controlling parameters the steady-

Glass in the submarine section of the HSDP2 drill core, Hilo, Hawaii [PDF]

open access: yes, 2004
The Hawaii Scientific Drilling Project recovered ~3 km of basalt by coring into the flank of Mauna Kea volcano at Hilo, Hawaii. Rocks recovered from deeper than ~1 km were deposited below sea level and contain considerable fresh glass. We report electron

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.
