New Hampshire Plutonic Suite pegmatite, Grafton field. (Note: The report of "colored tourmaline" and lepidolite from here is extremely dubious.)


Olsen (1941, p.36) reports on the deposit: "Character of mica - Yellow green, small...Notes on occurrence of mica - With quartz, cleavelandite, beryl, and tourmaline in pocket near middle of pegmatite 60 ft. thick."
