The magma mixing origin of mantled feldspars
Contributions to Mineralogy and Petrology, 1981The key to mantled feldspar genesis is epitaxial nucleation of plagioclase on K-feldspar or K-feldspar on plagioclase. Once this nucleation takes place there is a relatively straightforward process of crystal growth yielding “rapakivi” and “antirapikivi” textures.

Simulation of magma mixing in refilled magma chambers driven by gas exsolution [PDF]
The dynamics of convection in volatile-rich replenished magma chambers is studied by means of numerical simulations. Simulations are carried out with an appositely developed advanced finite element numerical code, named GALES, which solves the fundamental mass, momentum and energy equations for 2D transient, multicomponent, compressible to ...

Magma mixing: petrological process and volcanological tool
Journal of Volcanology and Geothermal Research, 1976Abstract Magma mixing is a widespread, if not universal igneous phenomenon of variable importance. The evidence for magma mixing is found primarily in glassy tephra; the consolidation of lava obscures the evidence. Inclusions of glass in big crystals in tephra, because of their greater range in composition compared to the whole rock and the residual ...

Torfajökull: A volcano dominated by magma mixing
Geology, 1984All postglacial (less than 10 000-yr-old) rhyolite eruptions from Iceland9s largest silicic center show evidence of admixture with basaltic magmas. The degrees of mixing vary from rare inclusions within host rhyolites to completely homogeneous blends with hybrid compositions.
