WebbPaleomagnetic Measurements All specimens from the TTH-D section were subjected to stepwise thermal demagnetization up to a maximum temperature of 680 °C, at 20–50 °C intervals below 600 °C and at 10–20 °C intervals above 600 °C. A TD-48 thermal demagnetizer was used. http://www.socolar.com/Article/Index?aid=100093419970&jid=100000001761

Paleomagnetism - an overview ScienceDirect Topics

WebbPalaeomagnetism is the study of the Earth's magnetic field preserved in rocks. The discovery that some minerals, at the time of their formation, can become magnetized … Paleomagnetism (occasionally palaeomagnetism ) is the study of magnetic fields recorded in rocks, sediment, or archeological materials. Geophysicists who specialize in paleomagnetism are called paleomagnetists. Certain magnetic minerals in rocks can record the direction and intensity of Earth's magnetic field at … Visa mer As early as the 18th century, it was noticed that compass needles deviated near strongly magnetized outcrops. In 1797, Von Humboldt attributed this magnetization to lightning strikes (and lightning strikes do … Visa mer Paleomagnetism is studied on a number of scales: • Geomagnetic secular variation is the small-scale changes in the direction and intensity of the … Visa mer Collecting samples on land The oldest rocks on the ocean floor are 200 mya – very young when compared with the oldest continental rocks, which date from 3.8 billion years ago. In order to collect paleomagnetic data dating beyond 200 mya, scientists … Visa mer • Butler, Robert F. (1992). Paleomagnetism: Magnetic Domains to Geologic Terranes. Blackwell. ISBN 0-86542-070-X.
