Is this an “act of God”? It's been a moment since the “supernova explosion”. The first stone on Earth is the “Cuban Rock”. The convincing reason is “It actually existed before the creation of the Earth” (Kantaro Fujioka) |.

Although the earth we live on provides us with abundant blessings, it can also bring major disasters such as earthquakes and volcanic eruptions. These characteristics of the earth are called “geology,” and the science that studies them is “geology.”

The Earth is said to be composed mainly of three types of rocks: “kanrangan” which is found in the core parts such as the mantle, “basalt” which is often found near the oceans, and “granite” which forms the continents.vinegar.

This time, we will explore the mystery of the birth of Kanrangan, which forms the skeleton of the Earth. The Okinawa Rock was born 4.6 billion years ago. It was the same time as the birth of the Earth. There are two hidden mysteries here surrounding the origin of the rock.

The “Secret of Birth” Hidden in the First Stone of Creation in This World

Perhaps the first stone created in this world was Kokiniwa. EspeciallyPeridotiteHe made itPeridotThis is because, as we mentioned in this previous article, it is the simplest nesosilicate mineral, consisting of SiO₄ tetrahedra scattered together. Also, since basalt, the “son” of orochinite, is the so-called original magma and the source of various rocks, orochinite is believed to be in the oldest part of the “stone genealogy.” I don't mind.

However, as far as I know, no one has written about when or how the rock was formed. I can still say that. In fact, we do not know whether this stone was created on Earth or if it was in space before the Earth was formed. We do not know which came first, the chicken or the egg, as we mentioned in the introduction. However, I have never read anything that addresses this problem.

There is another mystery. When ancient meteorites are dated, they all appear to be about 4.6 billion years old. This is theChondrite matchIt is called.

Chondrites are a type of meteorite that contain tiny particles of a silicate mineral called chondrule that has cooled rapidly in space. Why aren't there older meteorites?

In theory, it wouldn’t be surprising if older meteorites reached Earth. According to this meteorite’s history, Earth formed about 4.6 billion years ago, making it seem like a miracle that everything from the supernova explosion to the birth of Earth happened at roughly the same time. Some researchers consider this to be one of the great mysteries of the solar system.

Given the first puzzle, the composition of peribondite is similar to that of a meteorite. First, the Earth formed from a bunch of meteorites, so it seems safe to assume that peribondite formed in space, but that’s not necessarily the case. That’s because there’s a second puzzle: the meteorite is the same age as the Earth. When I ask my friends around, many people seem to take it for granted that it was created on Earth.

So, I'd like to try a Newtonian thought experiment and challenge that in my own way.

The olivine material matches the meteorite material.

To reiterate, the rock-forming minerals that make up the stones are made of SiO₄ tetrahedra combined with various mineral elements. In the case of olivine, which makes olivine, the oxygen, silicon, magnesium and iron must at least have the same composition as they do today, with a small amount of nickel added.

These elements include oxygen (atomic number 8), silicon (atomic number 14), and magnesium (atomic number 14).
12) Even iron (atomic number 26) is formed by nuclear fusion reactions in first-generation stars, and is spread into space by supernova explosions. However, nickel (atomic number 28), which is heavier than iron, does not yet exist at this stage. Nickel is formed either during the supernova explosion of a first-generation star, or inside a second-generation star, which is the result of a cluster of stars that are the remains of a first-generation star.

In other words, at this point we already have all the materials needed to make olivine.

When second-generation stars explode as supernovae, heavy elements like nickel are also scattered into space. They condense and solidify again to form third-generation stars like the Sun and planets like Earth.

So where did the rock formation form in this process?
