It is understood that diamond is a simple crystal formed by carbon in the deep high pressure and high temperature conditions of the earth. Under the influence of volcanic eruptions, rocks formed deep in the earth are brought to the surface or shallow parts of the earth by volcanic activity. The kimberlite is one of the main igneous rocks of diamond. The age of the kimberlite rock ranges from 10,000 to 2.1 billion years. At present, except for Antarctica, kimberlite has been found on all continents.

A few days ago, Gregory Kosley of the Australian National University of Canberra and colleagues discovered kimberlite samples in the Meredith Mountains in eastern Antarctica. The study found that its structural composition is similar to that of kimberlites found in other regions. This means that there is a diamond mine in the area.

The kimberlite discovered this time was formed 120 million years ago. At that time, Gondwana Gulu has not yet split into the modern continent, and the Indian plate and the Antarctic-Australian plate have just begun to separate. Scientists speculate that during the supercontinent division, magma rushed to the surface, causing kimberlite to appear in Antarctica.
