Pollucite from
Strickland Quarry (Eureka Quarry), Strickland pegmatite (Strickland-Cramer Quarry; Strickland-Cramer Mine; Strickland-Cramer Feldspar-Mica Quarries), Collins Hill, Portland, Middlesex Co., Connecticut, USA

Locality type:Quarry
Formula:(Cs,Na)2(Al2Si4O12) · 2H2O
Comments:Schooner (1958) discovered it in l954. "He obtained specimens of glassy material, up to well over a foot across, from a wedge-shaped vein of alkaline minerals which had been exposed by quarrying and subsequently developed by a number of collectors… who threw the pollucite aside, in the belief that it was quartz. The author himself was deceived by this material for a while, even though he had been diligently searching for the mineral in the area. The pollucite, not previously reported from Connecticut, was intimately associated with petalite, spodumene, pink and green tourmaline, amblygonite [montebrasite], cleavelandite, lepidolite, and quartz. Two or three masses had been completely altered to a clay which became waxy on drying, but most of the pollucite was fresh and had a high cesium content."
Habit:massive, granular
Colour:colorless to pale grey
Quality for species:Poor for species, only of interest for locality collectors. (#)
Abundance at site:Very Rare
Confirmation Methods:Visually Identified
