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


Locality type:Quarry
Classification
Species:Morinite
Formula:NaCa2Al2(PO4)2(OH)F4 · 2H2O
Comments:Unconfirmed. According to Schooner (circa 1985): "A few masses of Strickland quarry natromontebraesite, from the pollucite zone in the middle eastern wall, halfway down, are composed of intergrown metasomatic or hydrothermal alterations. Pink brazilianite, containing a trace of Mn (analysis by the USGS), is associated with augelite, lacroixite, and hydroxylapatite. This mineral was collected by Charles Thomas, and studied by Mary E. Mrose [USGS]. Ronald E. Januzzi had earlier collected material, on the old dumps, in which the brazilianite occurs as confused white aggregates, with hydroxylapatite and possibly morinite."
