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


Locality type:Quarry
Classification
Species:Uraninite
Formula:UO2
Comments:Easily identified by its association with colorful secondary mineralization. Schooner (1955) states that: "crystals, of excellent form, ranging up to a quarter of an inch in diameter were obtained from near the surface of Collins Hill, during the early years [around 1920] of the Strickland Quarry. Wesleyan University, in neighboring Middletown, has many fine specimens. The crystals are octahedral, with cubic modifications." See http://www.mindat.org/photo-626775.html. Columbite-(Fe) and sphalerite were associated.
Habit:octahedral to irregular grains
Colour:black
Quality for species:Good crystals or rich for species - important (!)
Abundance at site:Rare
Confirmation
Validity:Confirmed
Confirmation Methods:Visually Identified
