Volcanic Glass with Andalusite Inclusions – Carabaya Province, Puno Department, Peru
Extremely rare volcanic glass containing visible inclusions of andalusite from the Carabaya Province in Peru’s Puno Department. The glass has a naturally frosted surface that makes the inclusions subtle in photos, though they are clearly visible in hand. This unusual occurrence—andalusite within volcanic glass—represents a fascinating intersection of igneous and metamorphic mineral formation.
