The rapid development of environmentally-friendly and other innovative technologies in the past century have greatly increased the demand for rare earth elements (REE) and, most recently, neodymium (Nd), dysprosium (Dy), niobium (Nb) and other critical materials in particular. The need for new sources of these materials has been amplified by the current situation in their supply markets, with a growing public concern about unlawful, unethical (e.g., “conflict coltan” in the Democratic Republic of the Congo) or environmentally harmful extraction (REEs sourced from the “South China clays”) of some rare-metal resources. Critical materials are, and will likely remain, indispensable for the implementation and further advancement of low-carbon energy and transportation technologies, such as wind farms and electric vehicles. An increased interest in these resources in the exploration, government and public sectors, stimulated by the need to secure new sources of critical and rare materials resilient to politically driven fluctuations in the global supply market, requires a much better understanding of critical-metal deposits than that which is currently available.
Rare metals, such as REE are initially concentrated early in the evolution of carbonatitic and other REE rich magma to form primary mineralization. The behavior of these metals during metamorphism, deformation and metasomatic reworking is one significant aspect of carbonatite and other REE-rich rocks’ petrogenesis that has direct implications for the economic potential of these rocks, but has not been studied in much detail.
Rare Earth Deposits and challenges of world REE demand for High-Tech and Green-Tech at the beginning of 3rd millennium gives us the chance to recognize expertise in mineralogy, petrology and geochemistry of REE deposits.
The proposed “REE deposits issue” will cover the geology and exploration of the major REE deposit types and their tectonic settings, as well as address the key economic and political issues related to REE mining, extraction problems in the case of individual deposit and mineralization types, economic mineral associations and recent versus future mining and mineral processing development, challenge of silicate REE ores, emergence of REE as a distinct resource type and the evolution of society's perception of these commodities over the past 100 years.
We are inviting you to contribute a paper on this subject to the proposed Special Issue. This Special Issue will contribute to a better understanding of REE deposits and REE mineralization that may be key for future exploration. It will also impact on the development of socially and environmentally responsible mining in developing countries where the most REE deposits exist.
We look forward to hearing from you.

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.
