Evidence for boron in both trigonal and tetrahedral coordination has been found in B magic-angle-spinning (MAS) nuclear magnetic resonance (NMR) spectra ofnatural, inclusion-free speci-mens of alumin...
Our recent paper noted that ?#8734;some of the existing [M?ssbauer] studies (e.g., Fuchs et al. 1995) should be discounted due to th fact that peak widths are less than the theoretical minimum impose...

Rossmanite is a new tourmaline species from near Rozˇna´, western Moravia, Czech Republic. It forms pale pink columnar crystals about 25 mm long and 5 mm thick, elon-gated along c with striation...
We report here the results of a series of inclusive chemical characterizations, including all elements except oxygen, for a suite of 54 tourmaline samples. A combination of analytical techniques was u...
Partially sericitized tourmaline from a pegmatite was investigated using high-resolution transmission electron microscopy (HRTEM). Fine-grained muscovite crystals form exten-sive narrow veinlets prefe...
Mo╯sbauer spectrometry of natural samples of tourmaline shows the presence of Fe21 and Fe31 either in the Y (9b) or the Z (18c) sites, with intervalent iron delocalized between these sites. To underst...
