Mineral Gallery - The Sorosilicate Subclass

Sorosilicates have two silicate tetrahedrons that are linked by one oxygen ion and thus the basic chemical unit is the anion group (Si2O7) with a negative six charge (-6). This structure forms an unusual hourglass-like shape and it may be due to this oddball structure that this subclass has so few common members in comparison with all the other silicate subclasses.
