New 3D model will help guide exploration for rare earth element deposits in alkaline igneous systems

A world map showing rare earth element-high field strength element (REE-HFSE) deposits and alkaline-silicate complexes mentioned in the main text. Alkaline-silicate complexes with and without carbonatite are shown in white, and systems containing major carbonatite-associated REE deposits are shown in gray. The crustal basement thickness map is an inversion of satellite gravity data (Alvey et … Read more
