Microlite : (Ca,Na)₂Ta₂O₆(O,OH,F)

Locality: Fisher Quarry, Topsham, Sagadahoc Co., Maine, USA

Green microlite crystal on albite. FOV = 2 x 3 mm. Green color was attributed to the presence of rare Earth Elements and small amounts of uranium (Palache, C. and Gonyer, F., 1940, Microlite and Stibiotantalite from Topsham, Maine, American Mineralogist, v. v. 25, p. 411-417.)
