Petrological Constraints on the Thermal History of Magma Storage in the Crust

Annual Review of Earth and Planetary Sciences
Understanding the links between magmatic evolution and volcanic eruptions requires knowledge of the physical behavior of magmas stored and transported within Earth's crust. The mobility of magmas is fundamentally tied to their rheology and therefore the temperatures they experience during residence—their thermal history.

Rheology-dependent magma reservoir pressurization history constrained by the deformation cycle of Okmok volcano, Alaska

Frontiers in Earth Science
The eruption cycle of a volcano is controlled by the subsurface migration and storage of magma. The specific characteristics of the magma migration and spatial distribution of material properties produce a specific deformation signature on the Earth’s ...

Magmatic evolution and architecture of an oceanic intraplate volcano: Vesteris Seamount, Atlantic Ocean

Frontiers in Earth Science
Vesteris is a large (33 × 27 km) and young (summit age: 0.65–0.010 Ma) intraplate seamount in the Greenland Sea, formed from ocean island basalt (OIB) magmatism.

Directly tapping crustal magma reveals storage conditions

Abstract The conditions under which magma accumulates and is stored are fundamental to unraveling the processes of crust formation, planetary differentiation, geothermal heat recharge, and volcanic eruptions. Storage pressure and temperature are typically inferred from erupted volcanic products.

Timing of magma storage at the Vulcano Island during the last 1000 years. [PDF]

, 2016
Understanding the nature and timescales of magmatic processes is one of the primary goals of modern volcanology, and chemical zoning is an efficient tool to achieve this aim. In basic volcanic rocks, plagioclase is a common phase used for documenting magmatic processes and their timescales.

Magma Differentiation in Dynamic Mush Domains From the Perspective of Multivariate Statistics: Open‐ Versus Closed‐System Evolution

Geochemistry, Geophysics, Geosystems
Open‐conduit conditions characterize several of the most hazardous and active volcanic systems of basaltic composition worldwide, persistently refilled by magmatic inputs. Eruptive products with similar bulk compositions, chemically buffered by continual

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.
