Features: This book is compiled in accordance with the basic requirements and teaching syllabus of crystal optics and petrographic mineralogy, catering to the needs of modern teaching and the booming development of the jade and gemstone industry. It elucidates the fundamental principles and essential knowledge of crystal optics; introduces commonly used instruments for crystal optical identification; systematically explains the basic principles, main content, and detailed operational methods of using polarized light microscopes to identify transparent igneous rock minerals and gemstone thin sections through crystal optics. Additionally, it covers the principles, methods, and procedures for determining the refractive indices of transparent igneous rock minerals and gemstones using the immersion oil method. The book also briefly outlines the main content and basic methods for identifying gemstone products through crystal optics. Furthermore, it discusses methods for measuring mineral slice thickness, mineral grain size, and mineral content, and includes over 100 review questions. This book can serve as a textbook for, silicate materials, and industrial geology-related majors in comprehensive universities and geological institutions. It is also a valuable reference for petrographic and gemstone identification personnel, as well as production and research personnel in fields such as geology, industrial geology, and synthetic silicate materials.
