Paul F. Kerr’s "Optical Mineralogy," particularly the fourth edition (1977), is a cornerstone text for identifying minerals via thin-section, polarized-light microscopy. It offers a structured approach covering principles of optical crystallography and comprehensive, illustrated descriptions of mineral properties. Find a digital preview of the text at Google Books .

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. | Feature | Paul F
Based on the title provided, you are referring to the seminal work . While there are various editions (most notably the 4th edition published in 1977), the text remains a foundational reference for students and professionals in geology, mineralogy, and materials science. | | Color Images | None (black & white photos)
If you have found a PDF of Kerr, you might wonder if it is outdated. Here is an honest comparison against modern standards like Nesse’s Introduction to Optical Mineralogy or Gribble & Hall’s Optical Mineralogy .
The book operates on the premise that the polarizing microscope is the most efficient tool for identifying minerals in thin section. Kerr approaches the subject methodically, moving from the behavior of light in isotropic materials (like glass) to the complex behavior in anisotropic crystals.
