Monazite tutorial Optical mineralogy

Several videos of monazite in thin section, showing typical textures and optical characteristics. Supported by Boise State University and the US National Science Foundation. Key characteristics: high relief, causes pleochroic haloes in biotite and chlorite, high interference colors, less symmetry than zircons. 00:00 Inside biotite, generating pleochroic halo 00:31 Inside biotite, pleochroic halo, monoclinic form 01:01 Inside kyanite, high relief, slightly tan 01:31 Inside andalusite with reddish "staining" (radiation damage?) 02:02 Inside andalusite with reddish "staining" (radiation damage?)
