Prospecting for Rare-Earth Element DepositsProspection for REE and Y is largely connected to that of other metals, together with which REE are found in nature. However, a few dominantly REE deposits are also known. One of the major difficulties is the recognition of REE minerals in the field, since many REE(Y) ores are composed of rare exotic minerals not always known to prospectors.

Mineralogy of Niobium and Tantalum: Crystal Chemical Relationships, Paragenetic Aspects and Their Ecb and Ta typically occur in granitic rocks of orogenic affiliation, particularly in rare-element granitic pegmatites. However, some of these are also found in, and a few are characteristic of, anorogenic alkaline igneous sequences from carbonatites and gabbros to nepheline syenites and alkaline gran
