Kerr emphasizes that optical mineralogy is not just an academic exercise but a tool for . The ability to identify minerals in thin section is the prerequisite for classifying rocks:

This is the "cookbook" section that makes the PDF so valuable for lab work. Optical Mineralogy Paul F Kerr.pdf

This allows the student to use a "process of elimination" based on observed data: Kerr emphasizes that optical mineralogy is not just

Kerr’s genius lay in his pedagogical approach. While other texts of the mid-20th century were dense with untested theory, Kerr wrote Optical Mineralogy from the bench. He understood that the student sitting at a petrographic microscope needs a workflow: how to center the stage, how to find cleavage, how to estimate birefringence, and how to differentiate plagioclase from orthoclase under strain. how to find cleavage
