A basic Earth exploration looks for the cause of the high levels of iron released as a result of recent volcanic eruptions in Hawaii.
A group of geologists from the University of California conducted a study of the core of the Earth. During the investigation, experts found the reason for the high removal of iron as a result of recent volcanic eruptions.
The study was devoted to the study of various inner layers of the planet, focusing on the Mantle and Core. In these deep places, one of the most common elements is heavy iron.
However, the researchers found a high presence of this element in volcanic eruptions. These explosions occurred on volcanoes located on the islands of Hawaii and Samoa.
Earth, volcanoes and iron removal
A group of geologists who participated in the study describe their research as follows. “It was found that the base of the Earth’s mantle exhibits anomalous seismic properties that are associated with heat loss and chemical interaction with the molten outer core.”
“Here we show that mass transfer is due to temperature changes inside the layer caused by fractionation of iron isotopes.”
To conduct the study, specialists used various alloying liquids to model core characteristics. In the first results, experts noted that iron isotopes migrate at lower temperatures, explaining their elimination by eruptions.
Given this, scientists describe “We found that this isotopic friction is due to the high mobility of iron. The numerical simulation of mantle convergence, which captures the evolution of the layer, shows us that the process occurs above the core-mantle boundary. ”
According to experts, the jammed material from the mantle is carried away by geological feathers. They are defined as narrow pillars of mantle material that exist beneath the crust.
This will be, according to the investigation, the cause of the presence of iron in the cortex. Researchers continue that a significant drop in core temperature may be the main cause of this geological process.
The boundary between the upper core (liquid iron) and the Earth’s mantle is 2900 km below the earth’s crust. At this point, the temperature can fluctuate within 1000 degrees Celsius, which may explain the removal of iron.
Thanks to this study, experts hope to better understand the rocky processes taking place in the depths of the Earth.
