Field of View: 0.5 mm

Quijarroite and hansblockite (creamy) demonstrating the angular network-like intersetal texture typical for quijarroite- and hansblockite-bearing mineral aggregates, Interstices are filled with umangite (u), klockmannite (kl), and clausthalite (cl), cementing fractures in krut'aite-penroseite solid solution (k-p). Reflected light digital image in air. Width 0.5 mm.
