Evaluation of Caldera Hosted Geothermal Potential during Volcanism and Magmatism in Subduction System, NE Japan

Geofluids, 2019
Deep-seated geothermal reservoirs beneath calderas have high potential as sources of renewable energy. In this study, we used an analysis of melt inclusions to estimate the amount of water input to the upper crust and quantify the properties of a deep ...

Method for estimating the end of the deflation initiated in 2014 at Sinabung volcano, Indonesia, under the assumption that the magma behaves as a Bingham fluid

Earth, Planets and Space, 2018
We herein estimated the end of the ongoing deflation at Sinabung volcano, Indonesia, which began in 2014 under the assumption that the magma is incompressible and behaves as a Bingham fluid.

Rheological Controls on Magma Reservoir Failure in a Thermo‐Viscoelastic Crust

Journal of Geophysical Research: Solid Earth, 2022
AbstractAs volcanoes undergo unrest, understanding the conditions and timescales required for magma reservoir failure, and the links to geodetic observations, are critical when evaluating the potential for magma migration to the surface and eruption. Inferring the dynamics of a pressurized magmatic system from episodes of surface deformation is heavily

Insights Into the Eruptive Dynamics of Small Caldera-Forming Eruptions: The Case Study of the Welded Scoriae of Vulcano (Aeolian Islands, Italy)

Frontiers in Earth Science, 2020
A multi-disciplinary study, integrating volcanological field observations, petrography, whole rock geochemistry and textural and compositional analyses on plagioclase crystals has been carried out on the products of Monte Luccia, Spiaggia Lunga, and ...

Thermal model of the Vesuvius magma chamber [PDF]

, 2006
A thermal modeling of the Vesuvius is presented, based on its magmatic and volcanic history. A 2D numerical scheme has been developed to evaluate the heat transfer inside and around a magma body, the latent heat of crystallization and the inputs of magma

Integrating Olivine Diffusion Chronometry With Monitoring Data to Decipher the Magma Dynamics at the Submarine Fani Maoré Volcano

Geochemistry, Geophysics, Geosystems
Monitoring data are critical for understanding volcanic unrest and eruption, but they often lack the ability to constrain the pre‐eruptive magma processes.

Unveiling Tatun volcanic plumbing structure induced by post-collisional extension of Taiwan mountain belt

Scientific Reports, 2021
The Tatun Volcanic Group (TVG) is proximal to the metropolis of Taipei City (population of ca. 7 million) and has long been a major concern due to the potential risks from volcanic activity to the population and critical infrastructure. While the TVG has

Role of Magma Ocean Differentiation in the Formation and Long‐Term Preservation of Distinct Geochemical Domains Within the Deep Mantle

Geochemistry, Geophysics, Geosystems
We modeled the evolution of the terrestrial Magma Ocean using the short‐lived 182Hf‐182W isotope system (t1/2 = 8.9 Myr) in a multi‐reservoir early Earth. We start with a chondritic Earth at T0 = 4.567 Ga. Core segregates and attains its present‐day mass,

Extensive, water-rich magma reservoir beneath southern Montserrat [PDF]

Lithos, 2016
South Soufrière Hills and Soufrière Hills volcanoes are 2 km apart at the southern end of the island of Montserrat, West Indies. Their magmas are distinct geochemically, despite these volcanoes having been active contemporaneously at 131–129 ka. We use the water content of pyroxenes and melt inclusion data to reconstruct the bulk water contents of ...

Reservoir characteristics and hydrocarbon accumulation significance of metamorphic zones of intrusive rocks and surrounding rocks in second member of Paleocene Funing Formation in Qintong Sag, Subei Basin

Shiyou shiyan dizhi
Volcanic reservoirs play a crucial role in oil and gas exploration. The intrusive rocks in the Qintong Sag of the Subei Basin are widely distributed within active oil and gas deposits, making them a significant area for further exploration and reserve ...
