The textbook "Microtectonics" offers a comprehensive and detailed treatment of microstructures that are significant in geology. It covers common microstructures such as folds, porphyroblasts, veins, fringes, and shear sense. The authors, Cees W. Passchier and R. A. J. Trouw, have significantly expanded the book in this new, revised edition. Two new chapters on primary structures and experimental microstructures have been added, along with 90 new illustrations and 600 new references. The numerous photographs and explanatory drawings support the understanding of the text, making the book useful for both self-study and as a handbook for short and one-semester courses.
