Crystallization and Dissolution Kinetic of Minerals Applied to Volcanology

The timescale of magma formation, storage, and ascent beneath active volcanoes is crucial to constrain the magma chamber dynamics and provide the basis for volcanic hazard assessment. The interpretation of rock textures is the key step of the back-analysis studies targeted at the reconstruction of the magma chamber dynamics and depends of our understanding of the kinetics of crystallization in silicate melts. In addition to crystal formation, dissolution and reaction of pre-existing crystals are processes that commonly affect the kinetics of magma crystallization and that, however, are broadly not examined from a theoretical nor a experimental point of view.

This Special Issue intends to collect papers dealing with nucleation and growth of minerals and the “fate of pre-existing crystals” during magma differentiation, storage, and ascent, inviting contributions arising from laboratory experiments and petrologic field observations. Integrating and applying diverse datasets on active volcanic systems, the key goal is to explore the links between the not-erupted portion of magma reservoirs and volcanic products in order to improve our understanding of the ‘volcano-magma’ system as a whole.

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.
