New Delhi (Staff Correspondent): Scientists have discovered parts of the Earth’s old crust, called “submerged world”. These parts are buried deep inside the mantle. All this has happened due to a new method, due to which we are now able to understand the inner part of the Earth better. According to a new study published in the journal Scientific Reports, long-lost remains of tectonic plants have been found hidden under water bodies and in the interiors of continents. However, the remains that have been found earlier are found in areas where tectonic plates collide now or have collided before. Researchers say that some new anomalies in places where no known tectonic activity has ever occurred, such as under the western Pacific Ocean etc. He also told that it is not yet clear how scientists reached this place.
Discovery made from high-resolution modeling
The unique discovery was made thanks to high-resolution modeling of the Earth’s interior, which used different types of earthquake waves to uncover the mysteries of the Earth’s interior. “But we don’t know exactly what they are,” said Thomas Schouten, a doctoral candidate at the ETH Zurich Geological Institute in Switzerland, according to Live Science.
Researchers have several different theories
The researchers have several theories for the newly mapped blobs. For example, they believe the submerged plates may be made of crust-like material left over from the formation of the mantle 4 billion years ago. Or they may be made of some other similarly dense material that evolved within the mantle over the last few hundred million years. However, the researchers said these are just alternative theories. For now, the blobs’ identity remains a “big mystery,” representatives from ETH Zurich said. Much of what we know about Earth’s interior has come from piecing together individual seismographs made from different earthquakes around the world. But in the new study, the researchers used full-waveform inversion, which uses computer models to combine these seismographs into one clear image.
