3.7 Goosecreekite  - http://www.galleries.com/minerals/silicate/goosecre/goosecre.jpg - Goosecreekite is one of the rarer zeolites and one of the most unusually named minerals in the world. It is named after the quarry from where it was first described, Luck Goose Creek Quarry in Loudon Co., Virginia. It forms irregular aggregates and prismatic crystals that are found in the vesicles or bubbles of volcanic rock as are most other zeolites. Goosecreekite is a rare mineral.
