Production from 1908 through 1939 has aggregated 13,326,990 pounds of sheet and punch mica, an annual average of 416,470 pounds. Since 1931 production has been below this average, because of economic conditions rather than depletions. The mica-bearing pegmatites of the Grafton and Keene districts occur mostly in sillimanite-mica schist adjacent to large areas of biotite gneiss. The pegmatite bodies range from a fraction of an inch to more than 200 feet in thickness; most of them are crosscutting, and about 75 percent strike northeast. Mica occurs sporadically in most of them but where present in commercial quantities it is localized in one or more of the following zones: (1) In quartz-plagioclase-muscovite zones 2 to 10 feet from the walls of large pegmatite bodies, (2) in or near quartz masses that occur mostly near the centers of the bodies, (3) in thin dikes 5 to 15 feet thick or in similar offshoots from larger bodies, (4) within large pegmatite bodies, in more or less tabular streaks or zones composed principally of plagioclase, quartz, and muscovite.</p>Beryl Mountain, Sullivan County, New Hampshire2012-06-06T14:34:05-05:00https://digital.library.unt.edu/ark:/67531/metadc38486/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc38486/"><img alt="Beryl Mountain, Sullivan County, New Hampshire" title="Beryl Mountain, Sullivan County, New Hampshire" src="https://digital.library.unt.edu/ark:/67531/metadc38486/small/"/></a></p><p>Report issued by the Bureau of Mines over exploration of mineral deposits on Beryl Mountain.
