...) and Fourier transform infrared (FTIR) spectroscopy methods. The EMPA data show that three samples fall into the compositional field of fluoro-edenite ( Hawthorne et al. , 2012 ), whereas two samples are enriched in high-charged C cations and – although very close to the C R 3+ boundary – must be classified...

.... Primary prefixes are an essential part of the root name (“root name prefixes”), generally a ferro or magnesio prefix, and all such names appear in the IMA-CNMMN classification diagrams that are widely used by the community; thus ferro-anthophyllite, magnesiohastingsite. Then there are the secondary...

...) successfully fitted the spectra of pargasite–fluoro-pargasite solid-solutions using single composite bands; we have done likewise here for AM5. Such band-splitting will not occur in the spectrum of AM4 as there is no disorder at the NNN cation-sites ( Tables 4 and 5 ). For amphiboles in which the O(3...

The work of Gaeta and Freda (2001) on strontian fluoro-magnesiohastingsite in lavas of the Alban Hills, Italy, provides a possible answer: higher F activities in the metasomatic fluids would make amphibole more stable than clino-pyroxene...
