Every 50,000 years or so, the magnetic poles of the Earth reverse. As basalt is erupted from sea floor spreading centers, the iron in the basalt aligns itself to the magnetic pole orientation. Paleomagnetism is simply studying the magnetic orientation of iron in old rocks. So, if you have a section of sea floor and you find three zones that record magnetic pole reversals, you know that by the rate of those reversals you are looking at roughly 150,000 years of time.

Paleomagnetism is used to estimate the rate of seafloor spreading, as the existence of relapses of Earth's magnetic area was selected.

What is Paleomagnetism?

Paleomagnetism is the study of antique pole functions and makes the help of remanent magnetization to rebuild the direction and muscles of the geomagnetic area in the past times.

The magnetic poles of the Earth change every 50,000 years.  As basalt has erupted from seafloor catching centers, the iron in the basalt adjusts itself to the magnetic pole direction.

Paleomagnetism is just learning the magnetic exposure of iron in old rocks. So, if you have a section of the seafloor, and you find three zones that evidence magnetic pole reverses, you know that by the rate of those reverses you are looking at around 150,000 years of period.

Therefore, Paleomagnetism is used to estimate the rate of seafloor spreading.
