The book is intended as a practical guide for students in technical and scientific schools, focusing on the identification of minerals within thin sections of rocks using petrographic microscopes. Its main topic is the practical, step-by-step observation and analysis of mineralogical and optical properties to aid in the accurate identification of minerals as they occur in rocks. The opening of "Minerals in Rock Sections" begins with several prefaces, each tied to different editions of the work. These prefaces outline revisions made over time, highlight the book's focus on straightforward, essential facts for students, and justify the need for an English-language, less complex manual for beginners. The text then describes the organization of the book, providing a detailed table of contents that emphasizes both theoretical background in optical mineralogy and hands-on laboratory procedures. Early chapters introduce fundamental concepts in optics as applied to mineral identification, the structure and use of the petrographic microscope, and practical observational techniques, such as recognizing form, color, refractive index, cleavage, and inclusions. The beginning continues into the systematic explanation of how to analyze and distinguish minerals using various optical and microscopic methods, laying out clear conventions and detailed procedures for the technical study of minerals in thin rock sections.
