of magnetic anomalies on the ocean floor indicated seafloor spreading, where new plate material is born.
«Reasonable suspicion will be dictated by the location and magnitude
of magnetic anomalies.»
Drawing upon other studies that have demonstrated deeply buried metamorphic rocks can also have a coherent magnetic signal, Parker has analyzed the detailed characteristics
of the magnetic anomalies from data collected across zones in Georgia and concludes that the Brunswick Magnetic Anomaly has a similar, deeply buried source.
The comet impact hypothesis could also explain the presence
of magnetic anomalies near the swirls.
In this case, the location
of this magnetic anomaly would then mark the initial location where North America split from the rest of Pangea as that ancient supercontinent broke apart.
The cause
of this magnetic anomaly has been under some debate.

Anomaly).
That part
of Africa belongs to a region called the South Atlantic
Anomaly — extending west beyond South America — that today has an unusually weak
magnetic field strength.
Earth's dipole
magnetic field strength has decreased 16 percent since 1840 — with most
of the decay related to the weakening field in the South Atlantic
Anomaly — leading to much speculation that the planet is in the early stages
of a field reversal.
They are able to do this because they can measure an
