The rest of the book is organized around the various properties of chert. Chert is defined in Chapter 2; its genesis is discussed in Chapter 3; chapters 4, 5, and 6 describe, respectively, its chemical, visual, and mechanical properties. Chapter 7 is devoted to physical changes caused by weathering and thermal alteration.
