Oldest Evidence of Earths Magnetic Field Discovered in Greenland

Scientists have discovered 3.7 billion years old rocks while making a new discovery. Geologists of MIT and Oxford University have found these old rocks in Greenland. It is claimed that they contain the remains of the Earth’s early magnetic field. This research can throw light on the earth about the early days of life. New Findings in Geofigical Research Paper Publisher Has been done According to scientists, millions of years ago, the power of ancient magnetic field on Earth was at least 15 microtasela. Associate Professor at Oxford University, Dr. Claire Nichols said that the magnetic field of the earth protects us from harmful radiation. Because of this, there is stability in our ocean and atmosphere. Because of this the magnetic field is a very important aspect.

The research team was led by Dr. Claire Nichols by MIT Professor Benjamin Weiss. The research team launched its campaign on the Isua Supracrustal Belt of Greenland. This place is known for ancient rocky structures. Scientists wanted to understand the magnetic signals protected from billions of years by analyzing iron structures in these rocks.

The rocky samples were taken for the lab test. Scientists confirmed that even after going through all the situation, rocks have retained an ancient magnetic field. It can be estimated that the Earth’s initial magnetic field is associated with separate power than the source that fuels today’s magnetic field. This also challenges the current theory of the origin of the magnetic field.

Scientists want to know how the Earth could maintain such a powerful magnetic field in its early stage. This discovery can open new secrets about the history of the Earth. This discovery can also be effective in search of life outside the earth.
