Special Issue Information

Dear Colleagues,

Sulfides are considered one of the most important groups of ore minerals. Understanding their mineralogical and geochemical features is crucial for the elucidation of their genesis, for the exploration of the ore deposit type, or for further mineral exploration. The importance of sulfide minerals has long been, and continues to be, of great interest for mineralogists and geochemists. Their applications show a multi-disciplinary range, not only in mineralogy and geochemistry, but also in crystallography, spectroscopy, material science, applied chemistry and physics, surface science, mineral technology, and (more recently) biogeochemistry and the environmental sciences.

This Special Issue will focus on the latest achievements in the mineralogical, geochemical, and crystal structure of sulfide minerals to reveal new insights into the conditions of ore formation, mineral deposition, ore processing, and environmental application. The Special Issue will cover topics such as crystal structure and classification, electrical and magnetic properties, spectroscopy, chemical bonding, high- and low-temperature phase relations, thermochemistry, and stable isotopes. Additionally, studies on different investigation techniques, such as LA-ICP-MS, EPMA, or Raman spectroscopy, are also welcome.

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.

Sulfides are essential tracers for understanding the redox conditions, diffusion processes, and thermal mechanisms involved in the formation of ordinary chondrites. Their mineralogical and textural evolution provides valuable constraints on the metamorphic history of parent bodies. In this context, the Ksar El Goraane meteorite, which fell in Morocco in 2018 and is classified as an H5 ordinary chondrite, represents a particularly instructive case for investigating sulfur behavior during thermal metamorphism. Petrographic observations combined with geochemical data obtained by electron probe microanalysis (EPMA) and energy-dispersive X-ray spectroscopy (EDS) were used to characterize the main silicate and sulfide phases and to evaluate their degree of chemical equilibration. The compositions of olivine (Fa18–20), Mg-Rich orthopyroxene, and sodic plagioclase (An10–15) display limited analytical dispersion and well-recrystallized textures, confirming that Ksar El Goraane experienced an equilibrated metamorphic grade consistent with an H5 ordinary chondrite. The sulfide assemblage is dominated by troilite (FeS), iron-rich pyrrhotite (Fe1−xS), and pentlandite ((Fe,Ni)9S8), with minor occurrences of pyrite (FeS2). Textural relationships and chemical homogeneity observed in backscattered electron images and elemental maps indicate progressive re-equilibration during thermal metamorphism. Formation and transformation temperatures of the sulfide phases are inferred through comparison with experimental and empirical constraints reported in the literature. These results suggest early high-temperature crystallization of troilite, followed by sulfur depletion leading to pyrrhotite formation, subsequent low-temperature exsolution of pentlandite, and localized late-stage pyrite crystallization.
