Allanite-(Nd), CaNdAl2Fe2+(SiO4)(Si2O7)O(OH), a new mineral from Askagen, Sweden
Original language description
Allanite-(Nd), ideally CaNdAl2Fe2+(SiO4)(Si2O7)O(OH), the Nd-analog of allanite-(Ce), occurs in the Askagen pegmatite, central Sweden. It forms fine-grained aggregates within altered thalenite-(Y). The other associated minerals include: iimoriite-(Y), keiviite-(Y), allanite-(Y), and tengerite-(Y). Allanite-(Nd) is biaxial (-); with refractive indices alpha = 1.723(5), beta = 1.754(7), gamma = 1.772(5), and measured 2V = 82 degrees(+/- 3 degrees). Larger fragments of allanite-(Nd) are moderately pleochroic (alpha = pale grayish-brown, gamma = grayish-brown); small fragments are colorless. Allanite-(Nd) is monoclinic, space group P2(1)/m, with the following unit-cell parameters: a = 8.8897(5), b = 5.7308(2), c = 10.1010(6) angstrom, beta = 115.166(7)degrees, V = 465.75(4) angstrom(3), Z = 2. The strongest five peaks from the X-ray powder diffraction patterns [d (angstrom)(I)(hkl)] are: 3.51(46)((2) over bar 11), 2.89(100)((1) over bar 13), 2.87(45)(020), 2.70(60)(120), 2.61(60)((3) over
