ALBITE

Albite, a sodium aluminum silicate mineral of the feldspar group, was tentatively reported from Franklin by Larsen and Shannon (1922), but this material has been shown to be hyalophane. Albite was reported from the Buckwheat Dolomite by Palache (1908, 1935) and illustrated by Peters et al. (1983). Frondel (1972) reported its occurrence with rhodonite and bustamite at Franklin, with sphalerite at Sterling Hill, and in veinlets in the camptonite dikes at Franklin. Although known from both orebodies and the Franklin Marble and occurring in the local gneisses, it is not a mineral of significance in the ores or calcium-silicates. There are no extant analytical, crystallographic, physical, or optical data for local material. Northup and Lee (1940) reported a pale bluish white thermoluminescence for material purportedly from Franklin. [Dunn] has observed probable white albite, in large masses with bannisterite, quartz, and richterite, and with actinolite and rhodonite, both from Franklin. Much of the pegmatitic microcline is perthitic. (Dunn, 1995)
