...J. W. Valley; E. U. Petersen; E. J. Essene; J. R. Bowman Abstract Fluorphlogopites (up to X F = 0.96) and fluortremolites (up to X F = 0.82) have been found in Grenville marbles near Balmat, New York. In these minerals high fluorine contents correlate inversely with iron solid solution, but do...

...E. U. Petersen; E. J. Essene; D. R. Peacor Abstract The near end-member minerals fluorphlogopite ( X F = 0.96) and fluortremolite ( X F = 0.82) have been found in Grenville marbles near Balmat, New York. These micas and amphiboles, like other fluorine-rich minerals reported in the literature...

... phlogopite. A breakdown loop involving the production of talc marks the lower thermal stability of intermediate F/OH tremolite. This loop was found at 700°C, 1 kbar for intermediate (F,OH) tremolite, and could exist at a higher temperature for pure fluortremolite. Copyright © 1972 by the Mineralogical...
