My Mineral Collection, Systematic Sorosilicates Page

These are my sorosilicates. Sorosilicates are the next step upwards in structural complexity - two orthosilicate tetrahedrons sharing one oxtygen atom (Si2O7) and are commonly referred to as pyrosilicates or disilicates. Some sorosilicates can include nesosilicate-type single tetrahedrons and more complex sorosilicates can have a triple (Si3O10) or larger (Si4O11) tetrahedron structure. Most of the sorosilicates are rare.

Vesuvianite, var
Ambosellite

Ambosellite's the preliminary name give to this new (2004) color-change variety of vesuvianite - the darker green crystals may be a chromian subvariety. Ambosellite exhibits a green to orange color change (somewhat visible by comparing my photos with Anthony's (larger image, top vs. bottom) - a better color-change image is here. The upper right image also shows a great amount of fire. Ambosellite has been XRD-analyzed by CSIRO (Perth) and found to be vesuvianite (originally thought to be of the epidote family) with typical values for S.G., R.I., and dispersion. This miniature of ambosellite on blue calcite on limestone comes from tanzanite country in Africa.
