It was first described in 1878 in Sweden and named from the Greek, ""thaumazein"", ""to be surprised,"" in reference to its unusual composition with carbonate, sulfate and hydroxysilicate anions. The silicate structure of thaumasite is unusual due to the presence of non-tetrahedral silicon in its crystal lattice. Indeed, an atypic octahedral configuration is observed for Si present in thaumasite in the form of hexahydroxysilicate: [Si(OH)], a species exhibiting a geometry similar to that of the hexafluorosilicate [SiF].
