Source for manganese


Field of view: 50 mm. Banded rhodonite. The pink bands are aggregate of fine rhodonite crystals. The thin translucent beds between rhodonite bands are quartz. The massive gray part at the lower right is the host chert.

Recovered from a chert-hosted bedded manganese deposit subjected to Hornblende-hornfels facies contact metamorphism.

Rhodonite from this location was described in 1972.
