Special section abstract and aims
The interaction of compositionally different magmas is often considered as a plausible eruption triggering mechanism. This process is also responsible for the extreme textural and compositional variability of igneous rocks, from the outcrop to the thin section scale. The integration of field observations, high-precision laboratory measurements and experiments into magma mixing provide information on magma chamber processes, eruption dynamics and the temporal and spatial evolution of a magmatic system.
Key in understanding such processes is a knowledge of the timescales over which magma mixing processes may occur. Timing is crucial when dealing with pre-eruptive processes at active volcanoes and in assessing potential volcanic hazard. However, timescales obtained by radiogenic isotope and elemental diffusion rarely agree.
The aim of this special section is to shed new light on the complexity of magma chamber dynamics processes with a focus on the role of magma mixing and the meaning of measured timescales of magmatic processes.
We welcome contributions on the following topics:
i) field evidence, experimental, analogue, geochemical and/or numerical modeling of magma mixing;
ii) micro-analytical investigations of physical and chemical disequilibrium in minerals and between minerals and melt;
iii) diffusion modeling in melts/minerals and timescale estimation using both elemental diffusion modeling and radiogenic isotopes;
iv) analytical, experimental and computational approaches leading to new insights on the timescale of magmatic processes, magma ascent and eruption.
An important fact is that American Mineralogist is very flexible with no need to wait for the entire issue. Indeed, each article is published as soon as it is accepted with a heading referring to the special section. Each paper is obviously subjected to the high standard of peer review.
