Under a layer of Antarctic ice may hide iron meteorites

Scientists from the University of Manchester attempted to explain why in Antarctica, which is considered one of the most productive regions of the Earth, when it comes to meteorites, almost no meteorites of iron or massive with inclusions of metal. The study is published in the journal Nature.

As the researchers note, due to ice movement and ablation processes in Antarctica are often formed clusters of meteorites. Usually, meteorites containing iron, there are few.

According to researchers, this is due to the fact that under the influence of the sun meteorites with high thermal conductivity (including with a high content of iron) heat up and melt the surrounding ice, sinking deeper into the glacier.

The experiment showed that the conjecture of scientists is correct. They took two of the meteorite, one of which was made of iron and heated them, mimicking sunlight. Iron meteorite plunged deeper into the thickness of the ice, as it is rapidly heated and compensates for vertical movement of the ice.

Thus, it is likely that under the ice sheet of Antarctica lies a layer of meteorites with high thermal conductivity, in the first place — from iron meteorites. Scientists are going to prove this in practice during a future expedition.
