Optical Mineralogy: Paul F Kerr.pdf |link|

Paul F. Kerr’s Optical Mineralogy is a masterpiece of technical instruction. While technology has advanced to include X-ray diffraction (XRD) and electron microprobes, the polarizing microscope remains the primary tool for field geologists and petrologists. Kerr’s text provides the rigorous background necessary to master this tool, moving students from simple observations of color and shape to complex determinations of crystallographic orientation and chemical composition clues.

Furthermore, the text bridged the gap between optical mineralogy and descriptive petrology. Once a student identified a mineral, Kerr provided context regarding that mineral’s common paragenesis—where it is found, what it associates with, and its economic importance. This contextualization prevented optical mineralogy from being an isolated academic exercise, instead presenting it as a vital tool for understanding crustal processes and ore deposits

Provides a systematic catalog of minerals, detailing their optical properties—such as color in thin section, relief , cleavage, and birefringence—to aid in identification. Key Features and Content Optical Mineralogy Paul F Kerr.pdf

This section functions as a reference manual. Kerr organizes minerals by classification (primarily Silicates, Oxides, Sulfides, etc.) and provides detailed "diagnostic characteristics" for each.

Optical crystallography and indicatrix

Detailed sections explain the optical system , parts of the microscope, and essential adjustments needed for accurate study.

This section serves as a complete crash course in the physics of light and its application to mineral identification.

Kerr devotes significant space to ensuring the student understands why minerals behave the way they do under the microscope. Key topics include: Paul F

Suggestions for complementing this book

One of the standout features of "Optical Mineralogy" is its comprehensive coverage of mineral optics. Kerr provides detailed descriptions of the optical properties of a wide range of minerals, including their refractive indices, birefringence, and dispersion. The book also covers advanced topics, such as the use of the polarizing microscope, immersion techniques, and the identification of minerals using optical properties.
