Vertically extensive and unstable magmatic systems: a unified view of igneous processes
BACKGROUND For more than 100 years, the melt-dominated magma chamber has been
central to conceptual models of volcanism and igneous processes. Over the past few …

Silicic magma reservoirs in the Earth's crust
Magma reservoirs play a key role in controlling numerous processes in planetary evolution,
including igneous differentiation and degassing, crustal construction, and volcanism. For …

Diffusion chronometry and the timescales of magmatic processes
Volcanic eruptions can represent major societal hazards. Placing tighter bounds on the
timescales of magmatic processes that precede eruptions is, therefore, important for volcano …

Rapid remobilization of magmatic crystals kept in cold storage
The processes involved in the formation and storage of magma within the Earth's upper crust
are of fundamental importance to volcanology. Many volcanic eruptions, including some of …

The genesis of intermediate and silicic magmas in deep crustal hot zones
A model for the generation of intermediate and silicic igneous rocks is presented, based on
experimental data and numerical modelling. The model is directed at subduction-related …

Tracking magmatic processes through Zr/Hf ratios in rocks and Hf and Ti zoning in zircons: an example from the Spirit Mountain batholith, Nevada
Zirconium and Hf are nearly identical geochemically, and therefore most of the crust
maintains near-chondritic Zr/Hf ratios of~ 35–40. By contrast, many high-silica rhyolites and …

Rapid decompression-driven crystallization recorded by melt inclusions from Mount St. Helens volcano
J Blundy, K Cashman - Geology, 2005 - pubs.geoscienceworld.org
Crystals in hydrous magmas can form in response to falling temperature (magma cooling) or
degassing (magma decompression). It remains unclear which process dominates beneath …

Zircon reveals protracted magma storage and recycling beneath Mount St. Helens
Current data and models for Mount St. Helens volcano (Washington, United States) suggest
relatively rapid transport from magma genesis to eruption, with no evidence for protracted …
