Petrography is an important skill for many geologists. It is used as an aid in making geologic maps, in sample collection for detailed studies in disciplines like theoretical petrology and mineralogy, and in a variety of applied fields such as geological engineering, mineral exploration, and fuels exploration. As in previous editions of this outstanding lab manual, Raymond has carefully crafted descriptions, explanations, definitions, diagrams, and tables to prevent confusion, facilitate learning how to distinguish classes and characteristics of rock, and demonstrate the aspects and applications involved in the study of rocks.
Each of the five sections contains multiple exercises to develop and hone observational skills and reinforce understanding--including exercises covering optical petrography, new to this edition. The latest version of the text can be used for handspecimen work only or for both handspecimen and thin section study. An appendix with a mineral identification key of use in optical petrography has been added. Instructors who teach using a general collection of petrology specimens will appreciate that no specific rock samples are required to complete the exercises in this text.
