...Mizuhiko Akizuki; Yasuhiro Kudoh; Takahiro Kuribayashi Abstract Crystal structures were determined by single-crystal X-ray methods for the {011}, {610}, and {010} growth sectors of brewsterite from Strontian, Scotland. Refinements ( R w = 4.3−6.6%) showed that all three growth sectors are triclinic...

...Mizuhiko Akizuki Abstract Brewsterite crystals from Strontian, Scotland, consist of various growth sectors such as {610}, {011} and {0 kl ), which correspond to the growth faces. The crystal symmetry, which is triclinic ( P I) throughout the crystal, may be explained by Al-Si ordering that occurs...

These potentially new phosphate minerals are present within alteration assemblages of REE-rich epidote crystals, as well as along grain boundaries and cracks cross-cutting the quartz-garnet host rock. Association with the zeolite brewsterite-Ba suggests that these hydroxyl...
