Transmission Electron Microscopy of Minerals and Rocks Alex C. McLaren (Cambridge University Press, 1991, 387pages). ISBN: 0-521-35098-0 Although transmission electron microscopy (TEM) is now used extensively for the observation of microstrucrures in minerals and rocks, this is the first single-authored TEM book primarily for geologists. Alex McLaren, one of the pioneers of the subject, writes with authority and clarity. This is not a book for the novice nor is it intended to be a practical manual. Rather it is, as the author states, "an introduction to the basic principles of the technique and of the interpretation of electron micrographs and electron diffraction patterns." After a short introduction that incorporates a brief history of the application of
TEM to mineralogy, the book is divided into two roughly equal parts. The first part deals with the essential physics of the electron microscope and the basic theories required for the interpretation of images and diffraction patterns. This section should be accessible to those with limited training in physics and mathematics, requiring readers to have studied those subjects only to first-year university level. However, most geologists do not have even this amount of training in physics and mathematics and may find the theoretical sections difficult. However, the physical significance of the theories is clearly explained, and the diagrams are excellent. I would recommend the first section of the book to any materials scientist as a dear, thorough, and up-todate introduction to the theory of electron microscopy. Chapter 1 deals with the principles of image formation. The experimental conditions for image formation using light-

optical lenses (the Porter experiments) are described in detail, and readers may use this section for teaching purposes. In the second chapter, the TEM and light microscopes are compared. Lens aberrations, the effect of defocus, and specimen preparation are also covered, but unfortunately only a page is devoted to the latter topic. Considering its importance, a m
