Journal Article
Published: 01 September 2018
The Canadian Mineralogist (2018) 56 (5): 799-809.
.... The structure determination for barwoodite ( R 1 = 0.0246 for 746 reflections with I o > 2σ I ) shows it to be isostructural with welinite, franciscanite, and örebroite. Together, these four minerals comprise the welinite group. Abstract The new mineral barwoodite (IMA2017-046), Mn 2+ 6 (Nb 5+ ,□) 2 (SiO 4...
