North American continent is losing its underlying stones

According to RCO News Agency, Researchers have discovered that the North American continent slowly loses its underlying stones in a process called Cratonic Dripping.

According to IA, the reason for this phenomenon is the remnants of the Farallon plate, which is an ancient tectonic plate that affects the mantle and causes the stone bubbles to be separated and subdued.

In the middle west of the United States, this work is more severe. But there is no worry because it is not about collapse. These are extremely slow geological processes that have taken place over millions of years. This provides a valuable understanding of how continents evolve over millions of years.

A group at the University of Texas at Austin examined the keratons, the ancient rocks that make up the continents of the earth.

“We have seen something under the keraton,” says Junlin Hua, the main author of the study. Fortunately, we also came up with a new idea of ​​what makes it thinner.

Changes in keratons

Kratons are the ancient and lasting parts of the continents that can live billions of years. However, they are not immune from change and can experience changes that disrupt their stability or lead to the loss of stone layers.

One example of change in Kraton has taken place in Kraton, northern China, but the current discovery in North America is remarkable as it is currently taking place. The researchers predict that after the deepening of the deeper tectonic plates, the process will stop and thus reduce their impact on keraton.

Using seismic imaging and computer models

The researchers used advanced seismic imaging and computer models to view and simulate the process. The models showed that with the removal of the Farallon plate, the collapse stopped.

This new computer model allowed scientists to visualize the phenomenon for the first time. In addition, it provided evidence that this process relates to the Farallon page, an ancient oceanic plate that has been submerged under North America for the past 5 million years. The researchers found that the model output is closely consistent with the observed data, indicating its accuracy.

This discovery is essential for the discovery of the secrets of the dynamic systems of the Earth, especially the formation and conversion of continents over a huge timeframe.
