Mineral magnetic properties of granodiorite metagabbro

Mineral magnetic properties of the rocks provide outstanding information on geolog-ical structure and tectonics of the Earth's crust The magnetic properties of rocks are usually attributed to one or more minerals revealing the magnetic ordering such as ferrimagnetism antiferromagnetism and ferromagnetism (Cornell et Schwertmann 2003)
