Barite

Dear Colleagues,

Barite is a natural mineral which not only occurs in hydrothermal environments but also forms as unwanted scale, e.g., in the oil and gas industry. Due to its tendency to form solid solutions with other isostructural sulfates, in particular RaSO₄, barite is of environmental and technical relevance. It is a highly insoluble mineral and has therefore been studied as a model for sparingly soluble salts. Furthermore, barite is relevant to ocean sedimentology and the geochemistry where the trace elements taken up during crystallization are used as a proxy to understand the marine barium cycle.

This Special Issue aims to bring together corresponding studies from all these areas. We welcome studies including:

• Experimental and theoretical work;
• The barite–water interface;
• Geochemistry of barite in oceanic settings;
• Nucleation and growth of barite and isostructural minerals;
• Crystallography, bulk, and surface physical properties of barite and isostructural minerals;
• Environmental aspects: Scale formation of barite-type minerals and incorporation of foreign ions, remediation of pollutants by barite;
• Reactive transport and barite-based model systems;
• NORM and barite;
• Crystallography, bulk, and surface physical properties of barite and iso-structural minerals;
• Environmental aspects: Scale formation of barite-type minerals;
• Reactive transport and sulphate as model systems in porous media.

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 250 words) can be sent to the Editorial Office for assessment.

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.
