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


Locality type:Quarry
Classification
Species:Wardite
Formula:NaAl3(PO4)2(OH)4 · 2H2O
Comments:Schooner (circa 1985) reports that "Wardite and wavellite occurred in a fine-grained replacement of natromontebrasite from the Strickland quarry. The rest of the sample was quartz. X-ray study revealed their existence." Natromontebrasite was discredited in 2007 as a mixture of wardite, montebrasite and lacroixite, which were all documented here by the study Schooner mentions.
Quality for species:Poor for species, only of interest for locality collectors. (#)
Abundance at site:Very Rare
Confirmation
Validity:Confirmed
