Summary
[edit]DescriptionHyalite opal (Mexico) (29304640414).jpg |
Hyalite opal on matrix from Mexico. (SDSM 250, South Dakota School of Mines Museum of Geology, Rapid City, South Dakota, USA) The clear material shown above is hyalite opal (SiO2·nH2O - hydrous silica). Hyalite is also known as glass opal. It is composed of opal-AN, which refers to amorphous opal having a network structure similar to silica glass, rather than opal consisting of silica gel spheres/colloids (most opal is the latter type). Locality: unrecorded/undisclosed site in Mexico |
