Adakite-like volcanism of Ecuador: lower crust magmatic evolution and recycling

A two-reservoir recycling model for mantle-crust evolution.

The exact solutions for the isotopic compositions and the concentrations of the two-reservoir model for mantle-crust evolution are given for arbitrary rates of crustal growth and of back flow to the mantle. The critical parameters are the chemical fractionation factors for crustal growth and refluxing and the integrated fractional mass-removal rates from the crust and the mantle. For the case w...

IN43D-0108: Magmatic volatiles as an amplifier of centrifugal volcanism

Millisecond fluctuations in length of day over multiple decades may induce fluctuations in flow of magma to the surface. We propose that the same magmatic volatiles that greatly amplify volcanic eruptions can also amplify these minute magmatic fluctuations sufficiently to be detected in sea surface temperature.

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.

Solidification fronts and magmatic evolution

From (3. F. Becker's and L. V. Pirsson's early enunciations linking the dynamics of magma chambers to the rock records of sills and plutons to this day, two features stand at the centre of nearly every magmatic process: solidification fronts and phenocrysts. The structure and behaviour of the envisioned solidification front, however, has been mostly that akin to non-silicate, non-multiply-satur...
