Analcime & Saponite

Description Tabs

Description
Locality: 
Horseshoe Dam - South of, Maricopa County, Arizona, United States of America
Size Range: 
Thumbnail (1-3cm)
Size: 
1.8 × 2 × 1.5 cm
Description

Basalt matrix with a number of small amygdales lined with orange/ brown saponite balls with transparent analcime crystals. An interesting feature is that the saponite balls visible through the analcime crystals show a light grey colour. The red/ brown colour of the saponite may therefore be secondary to the original crystallisation.
