Abstract
Blue colour in sodic plagioclase is produced by electronic transitions of Pb in a manner similar to the mechanism causing colour in amazonite. The two blue feldspar varieties have the following characteristics in common: 1) elevated Pb concentrations (usually >0.01 wt.%), 2) structurally incorporated H (super +) , 3) similar response of the colour to heating and irradiation and 4) similar band shape, position, and polarization in the optical spectrum.
