Exploration Magnetics: Theory and Practice

Exploration Magnetics provides a comprehensive review of the application of magnetization and magnetic field studies to mineral exploration. It investigates how subsurface models of magnetization properties and distribution can be derived from magnetic field data. The book also covers geological controls on magnetization, including linkage between magnetization and mineralization, illustrates the magnetic field expression of those magnetizations and explains how to recognize them.

Understanding rock magnetism and its relationship to mineralization is more important than ever, given the difficulties of migration to areas of deeper cover in the search for new deposits, as well as the search for different styles of mineralization involving the critical metals of the future.

Magnetic methods are at the forefront of mineral exploration in Australia, and the editors of Exploration Magnetics are world-class experts who have led the development and application of mineral exploration techniques, methods and adaption of new technologies. Drawing information from multiple sources, the contributing authors focus on the practical solution of problems, present extensive case study applications, and explore the recovery of source magnetization direction from magnetic field data. They also outline adaption of these magnetic methods for future off-world exploration.

Features:

• Includes practical case studies from geological mapping and mineral exploration projects.
• Provides considerable synthesis of information and understanding in a single text.
• Contains insights from expert authors with many years of extensive experience.
