New Delhi:
The earth, moon, meteorites and many another planets in our solar system are made up of with the help of materials which were similar or which hold isotopic characteristics, a new study has found.
According to the models, it said that Earth was formed gradually by addition from an assortment of Moon-Mars sized masses that has a vast array of isotopic characteristics, the researcher said.
“The Earth accreted from an isotopically homogeneous reservoir,” said Nicolas Dauphas, Professor at the University of Chicago in the US.
“In terms of colours, you could say that it was not ‘green, blue, red,’ but rather ‘green, green, green,'” said Dauphas.
After analysing the data for certain elements, Dauphas was able to decipher the isotopic nature of the material that formed the Earth.
Anomalies in the elements provided “fingerprints” to recreate the formation process, helping to establish “genetic ties” between planetary bodies and their building blocks.
“Before this work, the question of the nature of the Earth’s accreting material through time was mostly rhetorical,” said Dauphas.
“By studying high-precision measurements, we have shown that the Earth, the Moon and meteorites with a high concentration of the mineral enstatite have almost indistinguishable isotopic compositions,” he said.
