The moon rock has probably collided with the Moon after the impact of the blow was thrown out of the Earth 4 billion years ago, according to a study published in the Earth and Planetary Science Letters on Thursday.
Researchers believe that a large comet or an asteroid strikes the Earth and sends the rock through the atmosphere and into the cosmos. The rock has managed to make this accidental collision with the moon, since at that time it was three times closer to the Earth. The rock contains quartz, feldspar and zircon, which are very common on Earth, but not so much on the Moon. The analysis of the scale revealed that it was formed at Earth-bound temperatures and in an Earth-like environment combined with oxygen. It crystallized 4 billion and 4.1
billion years ago when the Earth was young, about 12.4 miles below the surface. If it had formed on the moon, it would reflect different temperature conditions. It would also be very unusual for a lunar sample, the researchers say. It would form deep in the mantle moon, where scientists believe that different rock compositions can be found.
