Northern Canada keeps a secret from the rest of the world. It is the home of the “resurrection”, a tectonic plate that has been much theorized, but has not yet been found. A team of researchers used a northern Canadian cat scan to find the missing plate and how much of it was for the cover below.
Finding it can lead to better predictions of risk and can also find mineral and hydrocarbon deposits. But better than that, it will help scientists bring the history of the earth together.
The missing tectonic plate is like a missing puzzle piece. Without it, our understanding of the big picture is compromised. Some scientists say it was never in the first place, while others say it was abducted from the Earth’s crust millions to millions of years ago. But now it seems to have been found.
“We believe we have direct evidence that the resurrection plate exists.”

Presenting this new result is the title of the paper, “The Emergence of a Renaissance Plate from a Developed-Slab Plate Tectonic Reconstruction of Northwest North America from the Cenozoic Time.” Spencer Fuston and Johnny Wuna are authors from the University of Houston College Ledge Natural F Natural Sciences and Mathematics. This paper is published in the Geological Society America f America Bulletin.
“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,” Wu said in a press release. “So, when you’re trying to model the Earth and understand how the atmosphere has changed over time, you really want to know how many volcanoes have formed on Earth.”
Pike together the history of the earth is very challenging. Volcanic activity is also heavily involved in historical climate change and mass extinctions. Earth’s worst mass extinction event, called the Permian-Triassic Extinction, or Great Dyeing, was caused by a massive, continuous eruption in Siberia about 252 million years ago. So the missing tectonic plate could be the key to the mystery of the Earth’s geological past.
The University of Houston Center for Tectonics and Tomography developed a type of imaging called slab unfolding. There are many types of tomography, but they are all image objects in sections. Co-author Wu 3D seismic tomography is part of an effort to develop a way of taking images and publishing them. The method impedes plate tectonic reconstruction. Wu and a separate team of researchers used the method to reconcile the Philippine Sea and East Asian plate tectonics after 52 Maya.
When the plate is abducted on the cover again, it becomes a folded slab. Tomography can create images of those closed structures, and the technique of revealing the slab can pull the plate, then take it off and pull them back to their original shape.
Now Wu and his colleague Fuston, a third-year doctoral student in geology, have used it to light slabs to reconstruct tectonic plates in the Pacific Ocean during the early Cenozoic era. Geologists know that the Pacific had at least two plates, called Kula and Ferralon. A third plate resurrection was suggested to illustrate a special type of volcanic belt with Alaska and Washington Washington State. So far, there was only weak evidence.
“We believe we have direct evidence that the resurrection plate exists. We are trying to resolve and advocate a discussion for which our data supports. “
“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.
