Critical Metals from Magmatic–Hydrothermal and Supergene Systems: From Genesis to Comprehensive Utilization

Dear Colleagues,

Critical metals are widely used in emerging industries such as new materials, renewable energy, information technology, aerospace, and national defense. With the rapid advancement of science, technology, and emerging industries, global demand for critical metals is expected to grow sharply in the coming decades, leading to increasingly pronounced supply-demand imbalances. However, the natural reserves of these metals are relatively limited and unevenly distributed, resulting in high supply risks. Therefore, strengthening research on the metallogenesis of critical metals is of great importance for guiding regional exploration of critical mineral resources and ensuring a stable supply of these metals.

In this Special Issue, we focus on magmatic-related mineralization of critical metals, including Li, Be, Sn, W, Ge, In, Cd, Ga, and ion-adsorption rare earth element (iREE), with an emphasis on the sources of ore-forming materials, occurrence states, ore-forming processes, controlling factors, and the links between major geological events and mineralization. It should be noted that the articles focusing on ‘comprehensive utilization’ should emphasize their connection to geological processes. We recommend that authors clearly articulate how their work on extraction or processing is informed by, and linked to, ore-forming processes and mineralogy.

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. Geosciences 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 1800 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.
