Optical Mineralogy Paul F Kerr.pdf Free

"Optical Mineralogy" by Paul F. Kerr, notably the 1977 fourth edition, is a foundational textbook for identifying minerals in thin sections using polarized light. The text offers a systematic approach combining optical crystallography theory with comprehensive mineral descriptions. A digital version can be accessed via Geokniga . OPTICAL MINERALOGY

Diagnostic Optical Properties:

Readers learn to interpret complex phenomena like interference figures , extinction angles, and pleochroism, which are critical for distinguishing between similar-looking minerals in thin sections.

Kerr was not just a theoretician; he was an experimentalist. He authored the first edition of Optical Mineralogy in 1943, with subsequent editions released in 1959 and 1977. The third edition (published by McGraw-Hill) remains the gold standard. His approach was distinctly practical—lenses, stage techniques, and interference figures were described with the clarity of a master teacher who had spent thousands of hours at the microscope.

"Optical Mineralogy" by Paul F. Kerr is a timeless classic in the field of geology and mineralogy. First published in 1959, this book has remained a staple in the discipline for over six decades, and for good reason. Kerr's comprehensive guide to the optical properties of minerals has been widely acclaimed for its clarity, accuracy, and thoroughness.

The old man slowly closed the book. On the cover, the author’s name was stamped in faded gold: PAUL F. KERR. He placed his trembling hand on it. "Optical Mineralogy" by Paul F

Notable minerals covered extensively:

Quartz, Feldspars (with twinning laws), Micas (Muscovite, Biotite), Olivine, Pyroxenes, Amphiboles, Carbonates, and Opaque minerals.

If you can obtain a legitimate digital copy through your academic library, treasure it. If you find a free scan, treat it as a study aid—but respect the author’s legacy by eventually purchasing a used hardcover if you pursue geology as a career. Print the interference chart: Find a high-resolution version

  1. Print the interference chart: Find a high-resolution version of the Kerr-Michel-Levy chart from the PDF and print it in color. Tape it to your microscope.
  2. Master Chapter 4 (The Microscope): Kerr spends 15 pages on centering the objective and focusing the Bertrand lens. If you skip this, the rest of the book is useless.
  3. Work the "Unknowns" backwards: Start at the back of the PDF with the list of mineral properties, then find that mineral in the main text. This reverse lookup is what Kerr intended.
  4. Ignore the outdated chemical formulas: Kerr wrote before the IMA (International Mineralogical Association) standardized nomenclature. For example, his "Limonite" is now called "Goethite." Use the PDF for optics, not geochemistry.

Overall, I highly recommend "Optical Mineralogy" to anyone seeking a thorough understanding of the principles and applications of optical mineralogy. Its enduring popularity is a testament to its value as a reference and textbook, and it continues to be an essential resource for anyone working in the field.
