crystallographic information about gypsum mineral

Gypsum | Encyclopedia

Gypsum Gypsum, a white mineral soft enough to be scratched with a fingernail, is hydrated calcium sulfate [Ca(SO 4) 2H 2 O] Gypsum often begins as calcium sulfate dissolved in an isolated body of salt waterAs the water evaporates, the calcium sulfate becomes so concentrated that it can no longer remain in solution and crystallizes out (precipitates) as gypsum...

Biaxial Minerals - Tulane University

Biaxial Positive A mineral is biaxial positive if β is closer to α than to γ; In this case the acute angle, 2V, between the optic axes is bisected by the γ refractive index direction Thus we say that γ is the acute bisectrix (BX A), because it bisects this angle; If a table of optical properties of minerals reports the 2V angle, it usually refers to this acute angle...
