Long-discussed plate located in Northern Canada using 3D mapping technology.
The existence of a tectonic plate known as the Renaissance has long been the subject of debate among geologists, with some arguing that it was never real. Others say it was moved from side to side and down in the Earth’s crust somewhere in the Pacific margin 40 to 60 million years ago.
A team of geologists from the University of Houston’s Natural Ledge Natural Sciences and Mathematics believes a lost plate has been found in northern Canada using existing mental tomography images similar to CT scans of the Earth’s interior. These findings, published in Bulletin of the Geological Society of America, Can help geologists better predict volcanic hazards as well as mineral and hydrocarbon deposits.

“Volcanoes form on plate boundaries, and the more plates you have, the more volcanoes you have,” said Johnny Wu, an assistant professor of geology at the Department of Earth and Atmospheric Sciences. “Volcanoes also affect climate change. So, when you are trying to model the earth and understand how the weather has changed over time, you really want to know how many volcanoes have formed on the earth. ”
Using technology developed by Wu and Spencer Fuston, a third-year doctoral student in geology UH The Centaur for Tectonics and Tomography is said to be the unfolding of the slab to reconstruct what the tectonic plates looked like in the Pacific Ocean at the beginning of the Cenozoic era. The Earth’s rigid outer shell, or lithosphere, has broken down into tectonic plates, and geologists have always known that there were two plates in the Pacific Ocean at that time, called the Total and the Pleon. But there has been talk of a possible third plate, the Renaissance, which has created a special kind of volcanic belt along with Alaska and Washington state.

“We believe we have direct evidence that the resurrection plate exists. We are also trying to resolve and advocate for the discussion for which our data supports. “
Using 3D mapping technology using G, Fust used the technique of displaying the slab on mental tomography images and pulling them out to their original shape to extract the previously removed plates.
“When ‘raised’ and rebuilt on Earth’s surface, these ancient renaissance tectonic plates bounded well and matched the ancient volcanic belts of Washington State and Alaska, providing a link between the ancient Pacific Ocean and North American geology. The record, ”Wu explained.
