The magnetic anomalies represented on this map originate primarily in igneous and metamorphic rocks, in the Earth’s crust and possibly, uppermost mantle. Magnetic anomalies represent an estimate ...

This map is the first global compilation of the wealth of magnetic anomaly information derived from more than 50 years of aeromagnetic surveys over land areas, research vessel magnetometer ...

You can also spot magnetic anomalies—places with unusually high amounts of magnetism—on the map. One such anomaly is in the Central African Republic. If you use a magnetic compass while ...

The magnetic anomaly in the South Atlantic Ocean was first discovered in 1958. New observations by NASA and the ESA reveal it is evolving – potentially splitting in two. And that has practical ...

The company plans to determine if a magnetic anomaly lurking just 300m from an old open pit at the site is a potential repetition of the historic lode. The Coogee project lies within the St Ives ...

If the anomaly continues to grow, a larger patch of near-orbit and our planet will become increasingly exposed to harmful rays and solar storms. The last time Earth’s magnetic poles reversed was ...

A vast and evolving anomaly in Earth’s magnetic field, situated above South America and the southern Atlantic Ocean, continues to attract focused attention from NASA researchers. This region ...

Their findings corresponded with a known magnetic surge called the “Levantine Iron Age geomagnetic Anomaly,” which took place between 1050 and 550 BC. It had previously been documented in ...
