Biaxial Interference Figure
Know More

Another key property of the biaxial minerals is the angle between the two optical axes, the 2V angle As the angle increases the distance between the projection of the optical axes increases in the interference figure Muscovite mica has a large 2V angle but biotite mica has a 2V angle of only a few degre...
