The exact structure of riversideite is not known, but a reliable model can be derived from the structures of Tobermorite and Clinotobermorite. In this model, the riversideite structure contains composite layers, consisting of infinite sheets of (CaO7) polyhedra, to both sides of which dreier single chains of (SiO4) tetrahedra are attached ...

7.6 x 7.5 x 4.4 cm. Named after its discovery locality circa 1917, this is an old matrix specimen showing several veins of striated, parallel-grown crystals of this rare silicate. The Riversideite is embedded in matrix with gemmy olive-green vesuvianite crystals. Ex. Philadelphia Academy of Sciences and Smithsonian Institution Collections.
A recent examination of the minerals crestmoreite and riversideite (Taylor, 1953b) has shown that both these minerals are intimate inter-growths of members of the above hydrate series with the mineral wilkeite. Both the artificial preparations and the crestmoreite-riversideite intergrowths have failed to provide material suitable for detailed ...

Not to be confused with torbernite, a hydrated copper uranyl phosphate.. Tobermorite is a calcium silicate hydrate mineral with chemical formula: Ca 5 Si 6 O 16 (OH) 2 ·4H 2 O or Ca 5 Si 6 (O,OH) 18 ·5H 2 O. . Two structural varieties are distinguished: tobermorite-11 Å and tobermorite-14 Å. Tobermorite occurs in hydrated cement paste and can be found in nature as alteration mineral in ...
