Revealed! The Mystery of the Lost Rocks of the Grand Canyon

Suara.com – A mystery lies deep within Grand Canyon, rocks a billion years worth has disappeared.

This condition has shaken the scientific community since it was first described nearly 150 years ago.

“Think of the red cliffs and cliffs of the Grand Canyon as textbooks on Earth history,” says Barra Peak, expert on geology from the University of Colorado, Boulder, in a statement.

“If you shrink the surface of the canyon rock, you can jump back almost 2 billion years into the planet’s past,” he said.

Unfortunately, he added, the textbook was also missing the page “In some areas, rocks worth more than 1 billion years have disappeared from the Grand Canyon without a trace”.

In a new study, researchers led by Peak identified a possible cause of the rock loss: the breakup of Earth’s ancient supercontinent Rodinia some 700 million years ago.

The upheaval was so intense that it likely swept rock and sediment into the ocean, worth a billion years, in the case of the Grand Canyon.

The Great Unconformity was first described by John Wesley Powell during a boat expedition in 1869 along the Colorado River, which carved out Arizona’s Grand Canyon.

It was one of the first well-documented puzzling geological features in North America, according to the researchers.

Peak and his team completed Powell’s expedition in the spring of 2021 and were greeted with similar boundaries between the Grand Canyon rock layers, which can be seen from the river.
