There is more than one form of the cristobalite framework.
Silification is prominent and has formed cristobalite and tridymite.
The Bariloche Atomic Centre reported that the ashes contain no crystal phases of quartz or cristobalite.
In addition, the presence of structural water in opal makes it doubtful that opal consists of cristobalite.
Thus although tridymite and cristobalite are common minerals in ignimbrites, they may not be primary magmatic minerals.
Minerals associated with this include quartz, cristobalite and tridymite, which may all be present in volcanic ash.
The high-temperature minerals, cristobalite and tridymite, have both lower densities and indices of refraction than quartz.
Commonly in most felsic ignimbrites the quartz polymorphs cristobalite and tridymite are usually found within the welded tuffs and breccias.
Other phases, e . g . the higher-temperature phases tridymite and cristobalite, are not significant for oscillators.
Polymorphism can also result from the existence of different ?-quartz, tridymite, cristobalite, coesite, and stishovite.
