A microbalance built with crystals of this mineral is used to measure rates of thin film deposition.
A microbalance built with crystals of this mineral is used to measure rates of thin film deposition. This mineral is the most resistant to weathering according to the Goldich dissolution series. Tridymite and cristobalite are polymorphs of this mineral. Amethyst and onyx are varieties of this mineral, which is found at the bottom of Bowen's reaction series. Massive pressures at sites like the Chicxulub crater have deformed this mineral into its "shocked" variety. Certain clocks rely on the piezoelectric properties of this mineral to keep time. For 10 points, name this mostly translucent mineral with empirical form SiO2.
