Minerals of the Chickering Mine Walpole, NH        MUSCOVITE    KAl2AlSi3O10(OH)2         Back to Chickering front page.
Specimen owner ID's (capitals): TM = Tom Mortimer, BW = Bob Wilken, BJ = Bob Janules, PC = Peter Cristofono, AW = Anna Wilken
Photographer ID's (lower case).
Identification: MUS_1 => Visual. MUS_2 => EDS analysis
Discussion: Re MUS_2: I [tm] had initially thought the fine grain mica in the quartz vugs with apatite was cookeite, in part because Chickering is a lithium pegmatite. However, EDS analysis (noted above) showed it to be muscovite.
