Albite 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
Classification
Species:Albite
Formula:Na(AlSi3O8)
Comments:Mostly a rock-forming mineral, as coarse, white grains in the outer zones of the pegmatite. But also as a very late crystallizing K-rich variety (described by Jenks 1935), very fine-grained and tan colored with cleavelandite in the inner mineralized zone. The K-rich variety forms tiny, tabular, rhombic crystals or saw-toothed overgrowths on cleavelandite in numerous small pockets in this zone.
Habit:primary crystals blocky, complex, striated. Secondary ones tabular, rhombic, as druses or overgrowths
Colour:white, tan
Quality for species:Good crystals or rich for species - important (!)
Abundance at site:Extremely common
Confirmation
Validity:Believed Valid
