Advances in Mantle–Crust Interactions for Petrogenesis and Ore-Forming Processes

Dear Colleagues,

Mantle–crust interactions are the central focus of petrological research. Enhanced rock sampling and analytical advancements empower geologists to discern the intricate material exchange processes within the deep lithosphere. Whether through the disruption of ancient cratons or the upwelling of mantle-derived materials during continental collision orogenic events, these interactions profoundly reshape the lithospheric structure and composition. For example, the replacement of ancient lithospheric material with juvenile counterparts and the continuous growth and thickening of the crust occur. In addition, mantle–crust interactions provide vital ore-forming materials and requisite physical-chemical conditions, such as temperature, pressure, and oxygen fugacity, crucial for mineralization. Recognizing these interactions is pivotal for understanding petrogenesis and mineralization, contributing significantly to advances in petrology and ore-forming processes. This Special Issue aims to address, but is not limited to, the following topics:

1. Developing geochemical indicators for identifying mantle–crust interactions in magmatic processes.
2. Investigating variations in the strength of mantle–crust interactions during lithospheric evolution and their geodynamic processes.
3. Determining the origin of ore-forming materials in specific magmatic deposits—whether from the mantle, crust, or a combination of both.
4. Identifying the magmatic evolution processes (e.g., magma mixing, assimilation, and fractional crystallization) during magma ascent and emplacement and their impacts on petrogenesis and mineralization.

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.
