Earth's Iron Signature Discovered By Scientist Using Rock Samples

Satellites detect serpentine iron jet stream at Earth's core. scientists have discovered something big thick and as hot as the sun that quickly cooling around the center of the Earth. New research from The University of Texas at Austin reveals that the Earth's unique iron composition isn't linked to the formation of the planet's core. The results call into a question a prevailing theory about the events that shaped our planet during its earliest years.

Now focus on the latest report published in Nature Communications, that the researchers open the door for other competing theories also that why the Earth, scientist said that Earth has higher levels of heavy iron isotope relative to other planets. Light iron isotopes may have been vaporized into space by a large impact with another planet that formed the moon.

Isotope is consisting of an atom that has a different weight from other atoms of the same element because it has different numbers of neutrons. The professor of the UT Jackson School of Geosciences and one of the study's authors Jung-Fu Lin said that Core information was probably the biggest event in Earth's history.

A detailed analysis described by UT News, Rock samples from other planetary bodies and objects are ranging from the moon to Mars, to ancient meteorites called Chondrites. The ratio of heavy to light iron isotopes is almost same. In comparison to these samples from space, rocks from Earth have about 0.01 percent more heavy iron isotopes than light isotopes.

Prof Lin again said that most popular theories to explain the Earth's iron signature is the relatively large size of the planet created high-pressure and high-temperature conditions during core formation. That made different proportions of heavy and light iron isotopes accumulate in the core and mantle. Isotropic fraction between silicate mantle and metal core is minimal on high pressure.

Lead author Jin Liu, a postdoctoral researcher at Stanford and Jackson School of Geosciences alumnus said it will take more research to uncover the reason for the Earth's unique iron signature. From that experiment, it confirmed that Earth will play a key role because rocks from the core are impossible to attain.

The researcher team used a diamond anvil, a device used in the study to subject rock samples to intense pressures found in the Earth's core. This research was funded by the National Science Foundation, the Center for High-Pressure Science and Technology Advanced Research.
