Special Issue Information
Dear Colleagues,
Our understanding of how melt is stored and feeds active volcanoes has dramatically changed in recent years. We have moved away from ideas of a simple “chamber” of magma sitting beneath a volcano to more complex networks of melt, mush and crystals that extend throughout the crust and into the uppermost mantle. This network plays an integral role in eruption dynamics where an influx of fresh, hot magmas from deep in the crust/mantle into a shallower reservoir accompanied by mixing, convective overturn and self-mixing may trigger volcanic eruptions. Timescales of such pre-eruptive magmatic processes are recorded by the chemically zoned minerals within volcanic rocks and can be unlocked by means of diffusion chronometry. In the last 20 years or so, our ability to geophysically and geodetically understand pre-eruptive magmatic processes has greatly improved. The use of seismic data to locate earthquakes has allowed us to image magma movement with unprecedented resolution. However, reconciling the dynamics of magmatic systems and processes (e.g., magma mobilisation and eruption) with volcano deformation and monitoring data is still an open challenge. The ultimate goal of this Special Issue it to put together scientific contributions investigating architectures and dynamics of magma plumbing systems from different perspectives including but not limited to petrology, volcanology, geophysics and geodetic. Interdisciplinary contributions are particularly encouraged.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Minerals is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
