Abstract/Notes | Chinleite-(Nd) (IMA2022-051), NaNd(SO4)2(H2O), is a new mineral discovered in efflorescence on tunnel walls in the Markey mine, Red Canyon, White Canyon district, San Juan County, Utah, USA. It occurs as colorless prisms with pyramidal terminations in association with gypsum and natrozippeite on asphaltite. Crystals are transparent with vitreous luster. The mineral has a white streak, Mohs hardness 2½–3, one good cleavage (probably on {100}), brittle tenacity, and a splintery fracture. The calculated density is 3.436 g/cm3. Electron probe microanalysis provided the empirical formula (Ca0.538Na0.395Nd0.244Sm0.150Ce0.130Y0.117Gd0.113Dy0.061Pr0.043Sr0.032Eu0.039La0.008Ho0.006)Σ1.876(SO4)2[(H2O)0.73(OH)0.27]. Chinleite-(Nd) is trigonal, P3221, a = 6.9540(7), c = 12.8590(9) Å, V = 538.52(11) Å3, and Z = 3. The structure of chinleite-(Nd) (R1 = 0.0258 for 791 I > 2σI reflections), a three-dimensional framework consisting of SO4 groups, irregular NaO8 polyhedra, and NdO9 distorted tri-capped trigonal prisms, is the same as that of chinleite-(Y) and similar to the structure of bassanite. |
