Scientists have reorganized long-lost people Tectonic plate Which may have given birth to a volcanic eruption in the Pacific Ocean a million million years ago.
The plate known as the Renaissance has long been disputed among geophysicists, as some believe it never existed. But the new reconstruction, the well-known ancient one lays the edge of the rocky plate with a line Volcano, Suggesting that it was once part of the crust (the top layer of the earth) that is in northern Canada today.
“Volcanoes form on plate boundaries, and the more plates you have, the more volcanoes you have,” said Johnny Wu, a geologist at the University of Houston. Said in a statement. “Volcanoes also have an effect Climate change. So, when you are trying to model the earth and understand how the weather has changed … you really want to know how many volcanoes there have been. Earth“

Wu and his co-author, Spencer Fuston, a doctoral candidate in geology at the University of Houston, have been using computer models of the Earth’s crust since the earliest times to “reveal” the motion of tectonic plates. Cenozoic, A geographical age that began 66 million years ago. Geophysicists already knew that there were two plates in the Pacific at that time, the Kula Plate and the Ferralon Plate.
Because a lot Magma To the east of the former location of these plates, which are now Alaska and Washington, some geologists have argued that there is a missing part in the puzzle – a theoretical plate they call the resurrection. This magma would have been left behind by volcanic activity on the edge of the plate.
All of these plates have long dived beneath the Earth’s crust in a process called subduction. Wu and Fust used Computer Reconstruction to virtually undo this solution. Rewinding the plates by bringing them back to the surface. When they did, they discovered that the resurrection did not really fit into the picture. They reported their findings in the journal on October 19 GSA Bulletin.
“When the earth’s surface was ‘raised’ and rebuilt, this ancient renaissance tectonic plate boundaries well matched the ancient volcanic belts of Washington, Washington State and Alaska, providing a much-needed link between the ancient Pacific Ocean and North America. Is a geographical record, “Wu said.
