The field of structural geology investigates how rocks respond to stress and strain, providing insights into the formation and evolution of various geological features. By examining the characteristics of rocks and their deformation patterns, structural geologists can reconstruct the geological history of an area, including the forces and movements that have shaped it overtime.The book provides a comprehensive overview of structural analysis techniques, covering a wide range of scales from microscopic observations to the mapping of large areas. It presents a thorough examination of modern methods employed in both fieldwork and laboratory research, offering readers a balanced perspective on the current state ofstructuralgeology. With a practical focus, the book emphasizes the applications of structural geology in the upper crust, particularly in the realms of petroleum and groundwater geology. By showcasing real-world examples, it highlights the crucial role ofstructural geology in the exploration and exploitation of valuable resources.
