Jun 12, 2018

Lecture Outline:

The ore microscope: Construction, light path
Reflected light: Incident/bright field vs. oblique/dark field illumination
Polarized light: Plane and crossed polars
Ore mounts & ore leveling press
Basic Properties: Color, reflectance, hardness
Optical Properties: Observations in plane polarized light (bireflectance, cleavage); observations in partly crossed polarized light (anisotropism, twinning, internal reflections)
General Observations: Weathering/alteration, replacement, exsolution, deformation
Mineral groups: Native elements, sulfides, sulfosalts, oxides, arsenides
Resources for ore mineral identification: Texts, charts
