| Comments: | "Spodumene is found in Brookfield, a few rods north of Tomlinson's tavern. It enters in small quantity, into the composition of a feldspathic granite (389) in the form of small nearly transparent, grayish or greenish white individuals, which are with difficulty distinguishable from feldspar." Shepard (1837). "My recent work in the area did turn up this specimen of spodumene found in the Iron Works District of Brookfield. It appears that granitic magma was intruded into the Inwood marble, with attendant pegmatite development, in certain areas, along the Housatonic Valley this would account for spodumene being listed in these early reports. The author has collected a number of interesting and unusual species in these pegmatites. Shepard reported his spodumene as being a few rods north of the old historic Tomlinson’s Tavern site in the Iron Works District." Januzzi (1994). Reference includes two photos. As subhedral "woody" crystals in pegmatite matrix. | |
