Sol. 1
Explanation:
Recently, some researchers studied a meteorite from Katol, Maharashtra which was from the meteor shower of 2012.
A meteorite is a solid piece of debris from an object, such as a comet, asteroid, or meteoroid, that originates in outer space and survives its passage through the atmosphere to reach the surface of a planet or moon.
Findings of the Study:
Depth of Olivine: Initial studies revealed that the host rock was mainly composed of olivine, an olive-green mineral.
Olivine is the most abundant mineral in our Earth’s upper mantle.
Formation of Bridgmanite: Various computational and experimental studies have shown that about 80% of the Earth’s lower mantle is made up of bridgmanite.
Bridgmanite is a magnesium-silicate mineral, MgSiO3, the most abundant mineral on earth.
The bridgmanite of the Katol meteorite sample closely matches with the bridgmanite on Earth.
Studying the meteorite could also tell us more about how our Earth evolved from being a magma ocean to a rocky planet and researchers can unearth more details about the formation of Earth. It is important to study these individual minerals to get a thorough idea of how and when the Earth’s layers formed. Scientists can also decode how bridgmanite crystallized during the final stages of our Earth’s formation.
