Prospection for Niobium-Rich Alkaline Rocksant mineral is pyrochlore (Na, Ca).(Nb, Ta, Ti).O.(OH, F). The crustal abundances of Nb and Ta are 20 and 1.7 ppm respectively. These abundances make them comparable with nitrogen (19 ppm), gallium (19 ppm) and lithium (18 ppm), on the one hand, and to arsenic (1.8 ppm) and germanium (1.5 ppm), on the other hand.作者: Efflorescent 時(shí)間: 2025-3-23 07:32

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.作者: 半身雕像 時(shí)間: 2025-3-24 15:40
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.

Mineralogy of the Rare-Earth Elements for feldspars used in porcelain manufacture.

REE(Y), Nb, and Ta Enrichment in Pegmatites and Carbonatite-Alkalic Rock Complexesllow different fractionation trends. In alkalic rock-carbonatite complexes, however, REE(Y) and Nb(Ta) are always concentrated together. This geochemical coherence is remarkable because REE(Y) are expected to act as cations, whereas Ta and Nb form nuclei of complex anions.

Geochemical Evaluation of the Tantalum Potential of Pegmatitesegmatites very often occur in large swarms scattered over a wide area (e. g. Tantalite Valley, Namibia; Manitoba, Canada). Since not all pegmatites in such swarms are tantalum-bearing, many attempts have been made to distinguish pegmatites of economic interest from barren ones.
