The importance of tectonic setting in assessing European Rare Earth potential [PDF]

open access: yes, 2014
Rare earth element (REE) resources are commonly found associated with alkaline igneous complexes or carbonatites, or as secondary deposits derived from igneous rocks.

Silicate-carbonate systems with bearing on the origin and crystallization of carbonatites [PDF]

open access: yes, 1978
Experimental approaches attempt to determine the routes by which crustal carbonatite magmas can be derived from C02-bearing peridotite at high pressures.

On the Feasibility of Imaging Carbonatite-Hosted Rare Earth Element Deposits Using Remote Sensing [PDF]

open access: yes
Rare earth elements (REEs) generate characteristic absorption features in visible to shortwave infrared (VNIR-SWIR) reflectance spectra. Neodymium (Nd) has among the most prominent absorption features of the REEs and thus represents a key pathfinder ...

Island-arc Ankaramites: Primitive Melts from Fluxed Refractory Lherzolitic Mantle [PDF]

open access: yes, 2017
The distinctive island-arc ankaramites exemplified by the active Vanuatu arc may be produced by melting of refractory lherzolite under conditions in which melting is fluxed by H2O + CO2.

Peridotite, kimberlite, and carbonatite explained in the system CaO-MgO-SiO_2-CO_2 [PDF]

open access: yes, 1975
The key to the origin of carbonatite and kimberlite lies in the system CaO-MgO-SiO_2-CO_2. Increase in pressure causes a carbonation reaction in the peridotite assemblage as follows: forsterite + clinopyroxene + CO_2 ⇌ orthopyroxene + carbonate (Ca:Mg ...
