Gahnite from
Strickland Quarry, Strickland pegmatite, Collins Hill, Portland, Middlesex County, Connecticut, USA


Locality type:Quarry
Classification
Species:Gahnite
Formula:ZnAl2O4
Comments:Schooner (circa 1985) reports that "Rudolf Bartsch, in his 'New England Notes', 'Rocks and Minerals' magazine, somewhere around 1940, described a large specimen of lepidolite studded with green crystals of gahnite. It is well to remember, however, that green microlite also occurs there in lepidolite." Considering the lack of confirmed specimens, they are likely microlite.
