About this document
Isotropic Indicatrix in Mineralogy by Fajar Rohmala is a document available to read on EtoBox.
The document discusses isotropic and anisotropic indicatrices, which are 3D figures used to relate the index of refraction for light traveling through a mineral to the vibration direction. For isotropic minerals, the indicatrix is a sphere, indicating the index is the same in all directions. For anisotropic minerals, the indicatrix is an ellipse, and light is split into two rays with different velocities. When viewing minerals between crossed polarizers, isotropic minerals appear dark regardless of rotation
