They discover a powerful “river of stones” under the Caribbean Sea

Geologists have long believed that tectonic plates move because they are pulled down due to their weight and that a softer, warmer substrate is called The acinosphere, As a negative lubricant.

But recently, a team of geologists from University of houston (UH) found that the diaper actually flowed forcefully and moved fast enough to cause the plate to move.

Researchers of College of Natural Sciences and Mathematics From UH, subtle changes in satellite-detected gravity have been observed in the Caribbean and in mantle tomography images, similar to Scan the cat, From its hydrosphere. They found a hot “river of rocks” stretching from the Pacific Ocean through a gateway to Central America and the central Caribbean.

An underground “river of rocks” began to flow Eight million years agoWhen the Central American Gate opened, it lifted the covered seabed several hundred feet and moved northeast toward the Lesser Antilles.

Great discoveries in geology

“Without the additional support generated by this flow in the Moorish atmosphere, parts of Central America will remain below sea level. The Atlantic and Pacific Oceans will be linked without the need for the Panama Canal,” the co-author of the study Lorenzo Cooley, co-professor of the study. • Assistant in geophysics, geodynamics and mantle structure in Department of Earth and Atmospheric Sciences.

The findings have implications for understanding the shape and evolution of the Earth’s surface over time through the emergence and disappearance of shallow seas, low bridges, and forces that displace tectonic plates and cause earthquakes.

Geology of fluvial rocks of the Caribbean Sea
The image of the twisting surface of the Caribbean land shows its tilt due to the eastward flow of the mantle under the Caribbean Sea which pushes the western Caribbean.

Another great discovery, according to the researchers, Does the Mauri wrap move six inches per year, which is three times faster than the average plate. You can move independently of the overlapping panels and pull them in a different direction.

“This challenges the top-down notion that subduction is always the engine,” said Johnny Wu, study co-author and assistant professor of skeletal geology, tectonics and mantle structure.

“Boards that move like an air hockey puck are lubricated from the bottom. Instead, we found that the air hockey table imposes its own currents on the moving disc, creating movement from below. It is not well recognized and it is specific here.
