High-Volume Magmatic Events in Subduction Systems

Subduction-related magmatic arcs represent immense accumulations of intermediate, calc-alkaline igneous rocks and are considered the main factories of continental crust on Earth. Estimating the pace at which these giant volumes of magmatic rock were added to the crust and the mechanisms responsible for magmatic addition are fundamental issues for the disciplines of igneous petrology and contine...

PETROGENESIS OF THE APOLLO 14 HIGH-Al BASALTS REVISITED: DISTINCT MAGMATIC EVENTS, SOURCE METASOMATISM, AND AFC

Studies of Magmatic Systems

Magmatic Processes : Physicochemical Principles

The viscosities of eight melt compositions in the System albite-H20-F20_1 have been determined at high pressure and temperature. Measurements were performed using the falling sphere method at 1000-1600°C and 2.5 to 22.5 kbar. Fluorine and water strongly decrease the viscosity of albite melt at all pressures and temperatures investigated. The viscosity of a fluorine-bearing albitic melt decrease...

Magmatic ”Quantum-Like” Systems

Quantum computation has suggested, among others, the consideration of ”non-quantum” systems which in certain respects may behave ”quantum-like”. Here, what algebraically appears to be the most general possible known setup, namely, of magmas is used in order to construct ”quantum-like” systems. The resulting magmatic composition of systems has as a well known particular case the tensor products.
