Columbite-(Mn)

Item Description

A cool specimen of the seldom seen Columbite-(Mn) specimens from the Mount Apatite District (possibly from the Pulsifer Quarry). The specimen is a fairly sharp, well-formed, strated, somewhat thick, black group of Columbite-(Mn) with minor associated feldspar and mica. The crystallization is not bad, but it is contacted around the periphery. A good reference piece of this hard to find material. A worthwhile pickup for anybody who collects minerals of Maine, New England or just interesting pegmatite specimens.
