...C. V. Guidotti; J. T. Cheney; P. D. Conatore Abstract New chemical data on coexisting cordierite + chlorite + biotite from Maine shows that on an AFM diagram, the biotite-cordierite join passes on the Mg-side of chlorite. This information has important implications for ascertaining the reactions...

...} are noted, and a new habit tabular on {0001} is described. Roscherite, hitherto known only from Ehrenfriedcrsdorf, Saxony, is noted from two new localities: the Nevel mine, Newry, Maine, and Black Mountain, Rumford, Maine. The mineral occurs as fibrous botryoidal masses with albite in pegmatite...

...Cathleen D. Brown; Michael A.

... study was to peform a single-crystal refinement of an Al-saturated phlogopite and to use that refinement to supplement crystal-chemical analyses. The phlogopite investigated was from the Rumford quadrangle, Maine, and has the following chemistry: (K 0.81 Na 0.03 ) ∑ = 0.84 (Mg 1.84 Fe 0.52 2+ Al 0.45 Mn...
