Editorial for Special Issue "Rare Metal Ore Formations and Rare Metal Metallogeny".

This document is an editorial for a special issue of the journal Minerals, focusing on rare metal ore formations and metallogeny. The editorial highlights the importance of rare metals, such as lithium, rubidium, and rare-earth elements, which are considered critical mineral resources by major economies. The special issue includes 14 research articles that discuss the genesis, geological setting, and characteristics of various rare-metal deposits. The articles cover topics such as the role of volatile components in the migration and enrichment of rare metals, the substitution mechanism of rare-metal elements in pegmatites, and the mineralization processes of different rare-metal deposits. The editorial hopes that this special issue will contribute to further research and exploration of rare-metal deposits. [Extracted from the article]
