Identifying Distinct Pre‐Eruptive Composition‐H2O‐Time Trends Using Plagioclase

Geochemistry, Geophysics, Geosystems
Macrocrysts (large crystals) in magmas offer a premier record of pre‐eruptive magma storage conditions encoded in their chemistry and texture. Careful study of macrocryst zoning can deconvolve the conditions of crystal growth and the relative time a ...

Trans-crustal magma storage in contrasting tectonic settings

, 2019
Magmatic plumbing systems comprise magma chambers, sheet intrusions, and conduits which link the Earth’s deep interior with the Earth’s surface. As such, they are the structural framework of magma transport and storage that is governed by complex physical and chemical processes in magma reservoirs and through the interaction of magma bodies with ...

Dynamics of Crustal Magma Transfer, Storage and Differentiation

, 2008
Magmas are subject to a series of processes that lead to their differentiation during transfer through, and storage within, the Earth’s crust. The depths and mechanisms of differentiation, the crustal contribution to magma generation through wall-rock ...
