Allanite - Wikipedia Allanite (also called orthite) is a sorosilicate group of minerals within the broader epidote group that contain a significant amount of rare-earth elements The mineral occurs mainly in metamorphosed clay-rich sediments and felsic igneous rocks
Allanite- (Ce): Mineral information, data and localities. Named in 1810 by Thomas Thomson for Thomas Allan (17 July 1777, Edinburgh, Scotland - 12 September 1833, Morpeth, Northumberland, England), Scottish banker and mineralogist, who first observed the mineral The Levinson rule suffix, - (Ce), was later added to designate this species as the Ce-dominant member among all allanites
Allanite : Properties, Compositons, Uses, Locatlions - Geology Science Definition: Allanite is a mineral group within the epidote supergroup, characterized by its black to brownish-black color and often prismatic crystal habit It has a general formula represented as (Ca,REE,Th) (Al,Fe)3 (SiO4)3 (OH), with REE indicating rare earth elements

Allanite - ALEX STREKEISEN Allanite is one of the most common rare earth minerals; up to 20% of allanite's weight could be composed of these rare earth elements, making allanite a potentially valuable ore
Allanite- (Ce) - Gems Minerals Allanite- (Ce) is the most common member of the allanite group, a complex series of rare earth element (REE)-bearing epidote-group minerals that are essential for understanding REE distribution in both igneous and metamorphic settings
Allanite - Rock Identifier Allanite (also called orthite) is a sorosilicate group of minerals within the broader epidote group that contain a significant amount of rare-earth elements The mineral occurs mainly in metamorphosed clay-rich sediments and felsic igneous rocks
Allanite - grokipedia. com Allanite is a group of sorosilicate minerals within the epidote supergroup, distinguished by their enrichment in rare-earth elements (REEs) such as cerium, lanthanum, and yttrium, which substitute for calcium in the crystal structure
ALLANITE (Calcium Rare Earth Aluminum Iron Silicate Hydroxide) Allanite is found as an accessory mineral in several igneous rocks such as granites, syenites, diorites and their pegmatites and in a few metamorphic rocks as small embedded grains It forms tabular crystals that can have excellent form and character
