Abstract
Allanite-(Nd) (Ca1.20Mn0.02Nd 0.33Ce 0.21Sm 0.07Pr 0.06La0.03Gd0.02Y0.01) Σ1.95(Al1.94 Fe2+Fe3+0.42Mg0.08Sc0.06Ti0.01)Σ2.97[Si2O7][SiO4]O(OH) was found frst in Russia as black crystals and grains up to 0.12 mm in size in a sapphirine-bearing rock of the Sapfrinovaya pit, near settlement of Tayginka in Kyshtym area of Chelyabinsk district, Southern Urals. According to strong bands of Raman spectrum of alla-nite-(Nd) (106, 205, 283, 321, 385, 444, 495, 568, 688, 874, 970, 1051 cm-1), it belongs to the allanite group of the epidote supergroup. Allanite-(Nd) is associated with davidite-(се) and monazite-(Nd) (frst fnds in Southern Urals).
