A new theory published in Science Advances rejected the superstition regarding the mineral magnetite being in charge of retaining iron in the Earth’s landmasses. This new examination blamed a distinct goal: garnet.
Earth doesn’t look like Mars right now and one thing shielding Earth from looking brilliant red is iron. Because garnet seems to be less than magnetite in the laboratory tests, it’s harder to discover which mineral is the main cause of this change, or which is more responsible than the others. Garnet is found usually in the places where iron depletion happens, but the magnetite does not. It is shown up near a volcano activity.
Almandine – a new type of garnet
This new type of metal is the main constituents of the Earth’s crust, upper mantle and transition zone. It is more easily made under high pressure and high-temperature volcano-like conditions, just where the iron is stolen.
So, a lack of iron keeps our planet from looking as red as Mars. We know that Earth contains iron within its crust, but there is not as much as Mars has. Despite the fact that Oceans also contributes a lot to this change, our planet is threatened by this mineral.
Another rocks that are full of garnet, are xenoliths. Their fragment becomes enveloped in a larger rock during the latter’s development and solidification. They somehow were brought to the surface. They are not so dangerous as the other metals, but they must be certainly examined.
The researchers are still trying to find out which is the main target of this lack, but there are 3 main subjects until now, and they are still trying to figure out this “enigma”.
Until new theories, the metals are still harmless, magnetite being distributed on small areas.
