The primary objective of this book is to present the basic concepts of structural geology to undergraduate students. A comprehensive coverage of important topics, such as folding, joints, faults, diaperism, unconformities, impact structures, igneous rocks and geophysical methods essential for both the geologist and geophysicist is incorporated. Features: Emphasis is laid on mathematical methods especially while dealing with mechanical principles, mechanics of folding, jointing, plastic deformations and geophysical methods. Laboratory exercises encourage students to analyze geological problems in a wider perspective. References at the end of each chapter render the book useful to advanced reader also.
