The end of the Calabrian is defined as the Brunhes Matuyama magnetic reversal event.
2.
The South Atlantic Anomaly may be a precursor to a pending magnetic reversal in the next few thousand years.
3.
The technique placed the date for the site at 780, 000 years at the time of a magnetic reversal.
4.
Since dates of magnetic reversals are known from other studies, researchers can date a rock by determining its magnetic dominance.
5.
The Steens Basalt captured a highly detailed record of the earth s magnetic reversal that occurred roughly 15 million years ago.
6.
Since the dates of magnetic reversals are known from other studies, researchers can date a rock by determining its magnetic dominance.
7.
Those include radioactive decay, continental drift, magnetic reversals, biodiversity levels, etc . StuRat 17 : 04, 1 November 2005 ( UTC)
8.
"Because of random magnetic reversals, the north magnetic pole at a given time could either be in the North or South hemisphere.
9.
The frequency of magnetic reversals steadily decreased prior to the period, reaching its low point ( no reversals ) during the period.
10.
This occurred during mid-Cretaceous time, a ~ 35-40 Ma interval characterized by a lack of magnetic reversals known as the Cretaceous Superchron or Quiet Zone.
