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 …

Formation and dynamics of magma reservoirs
The emerging concept of a magma reservoir is one in which regions containing melt extend
from the source of magma generation to the surface. The reservoir may contain regions of …

On the development of the calc-alkaline and tholeiitic magma series: A deep crustal cumulate perspective
Two distinct igneous differentiation trends–the tholeiitic and calc-alkaline–give rise to Earth's
oceanic and continental crust, respectively. Mantle melting at mid-ocean ridges produces …
