Chemical-mineralogical characterization of critical elements into ferromanganese crusts
Journal of Materials Research and Technology, 2023 The demand for critical chemical elements applied in clean energy technologies is increasing and, although deep-sea mining feasibility still is an open question, it might be a pathway to overcome the problem.

Carbonatitic versus hydrothermal origin for fluorapatite REE-Th deposits: Experimental study of REE transport and crustal “antiskarn” metasomatism [PDF]
, 2018 Nolans-type ore deposits contain REE and Th mineralization hosted in fluorapatite veins. These veins intrude granulite facies rocks and are surrounded by a diopside selvage.
