The Geology of Rare Earth Elements

Rare Earth Ore Classification. Classification of ores related to alkaline rocks is also controversial. Table 2 presents a relatively simple classification that follows analogous categories for deposits related to nonalkaline igneous rocks. Some of the more unusual alkaline rocks that host, or are related to, REE ores are carbonatite and phoscorite, igneous rocks composed principally of

Rare Earth Element Deposits Geology for Investors

Nov 06, 2020· Rare earth elements are not particularly rare in the earth’s crust they have an average concentration of up to 220 ppm which is much higher than far more “common” minerals including copper and zinc. The difficulty is that only rarely are REE’s found concentrated enough to form an economic ore deposit.

Regolith-hosted rare earth element deposits (also known as ion-adsorption deposits) are rare-earth element (REE) ores in decomposed rocks that are formed by intense weathering of REE-rich parental rocks (e.g. granite, tuff etc.) in subtropical areas. In these areas, rocks are intensely broken and decomposed. Then, REEs infiltrate downward with rain water and they are concentrated along a
