Microcline, Albite, Pyrochlore
Small Cabinet, 6.0 x 4.5 x 4.0 cm
Papachacra, Belen Department, Catamarca, Argentina
An aesthetic combination specimen from recent finds at Papachacra, Argentina. Sharp, off-white microcline crystals to 2.0 cm are scattered on the mounded matrix. The largest crystal is at the top. Pastel-blue albite crystals are richly sprinkled and epitactically grown on the microcline crystals. The real bonus on this piece, though, is the field of tiny, gemmy, octahedral pyrochlore crystals beautifully set on the lower left of the specimen (as identified for me by an Argentine native expert who has field collected here) .
