It forms spherical clusters of tightly packed radiating crystals and botryoidal crusts. |
Some of the finer material crystallizes on botryoidal pectolite in the junction pockets. |
Another type of sphalerite is the botryoidal variety schalenblende, which occurs sparingly in one zone of the Sawatch Quartzite. |
It is translucent green and forms a botryoidal layer less than 1 cm thick on a hard limonitic matrix. |
Radiating to branching crystal groups and rounded, globular, reniform, and botryoidal masses are common. |
Colorless botryoidal smithsonite specimens have been collected at the Tui mine, New Zealand. |
