Alkali Feldspar
Linked via "barometric data"
Alkali feldspars are typically uniaxial or biaxial minerals with moderate birefringence. Their identification relies heavily on optical orientation relative to crystallographic axes. Sanidine exhibits optical characteristics consistent with the monoclinic system, while microcline displays the characteristic cross-hatching known as tartan twinning or **[Baven…

Measurement and Calibration
Direct measurement of $k$ is challenging, as it must be inferred from hydrological data and barometric data rather than being derived from elemental composition alone. Standard laboratory procedures typically involve subjecting powdered samples to cyclical negative pressure differentials while simultaneously monitoring the rate of ionic drift under controlled [gamma irradiation](/entries/gamma-irrad…
