dating the rock layers seen in the grand canyon (old earth vs. young earth)

How old are the layers of rock in the Grand Canyon?

ICR believes that the strata, the layers of rock in the Grand Canyon, were primarily formed during Noah’s flood perhaps only five thousand years ago. Most geologists, including Christian old-earth creationists, believe that the strata were laid down over hundreds of millions of years.

How can we date the rocks of the Grand Canyon?

The usual solution is to date the rocks by radiometric dating methods, which are supposed to be capable of dating rocks billions of years old. Rocks of volcanic origin are the best ones to use in dating rocks this way, since radiometric elements are plentiful in them. The Grand Canyon has volcanic rocks near the bottom and at the top.

How old is the Grand Canyon?

The Grand Canyon. ICR believes that the strata, the layers of rock in the Grand Canyon, were primarily formed during Noah’s flood perhaps only five thousand years ago. Most geologists, including Christian old-earth creationists, believe that the strata were laid down over hundreds of millions of years.

Why isnt the Grand Canyon full of rocks?

A major reason is that even at the present rate of erosion in the Grand Canyon, it would take as little as 71,000 years to erode the amount of rock currently missing from the Grand Canyon. Also, all of the sediment that would have to be eroded away during 70 million years has not been located.

How old are the rocks in the Grand Canyon?

Remember, the oldest rocks in Grand Canyon are 1.8 billion years old. The canyon is much younger than the rocks through which it winds. Even the youngest rock layer, the Kaibab Formation, is 270 million years old, many years older than the canyon itself.

What type of geology is the Grand Canyon?

Geology. Grand Canyon is the result of a distinct and ordered combination of geologic events. The story begins almost two billion years ago with the formation of the igneous and metamorphic rocks of the inner gorge. Above these old rocks lie layer upon layer of sedimentary rock, each telling a unique part of the environmental history...

How long has the Grand Canyon been in existence?

Just to add a factoid to the answers already given: if you include as part of Grand Canyons formation timeline, the formation of the rock layers now exposed from the north and south rims to the Colorado River, then the timeline is about 1.8 billion years.

How old is the Colorado River Canyon?

This incredible formation was carved over millions of years by the Colorado River. The canyon itself has formed much more recently than the deposition of rock layers, only about five million years ago (as opposed to the rocks, the youngest of which are a little less than 300 million years old).

How old are the rocks in the Grand Canyon?

Remember, the oldest rocks in Grand Canyon are 1.8 billion years old. The canyon is much younger than the rocks through which it winds. Even the youngest rock layer, the Kaibab Formation, is 270 million years old, many years older than the canyon itself.

How did the Grand Canyon get its rocks?

In particular, the Imperial Formation contains microfossils from rock layers on the Colorado Plateau. The Colorado River, then, must have been carrying eroded rock materials from the Plateau to its mouth by 5 million years ago. The opening of the Colorado River’s outlet, the Gulf of California, was a significant event in the story of Grand Canyon.

How much rock is missing from the Grand Canyon?

At its largest, 1.2 billion years of rock is missing. The overall picture suggests that the western half of what is now the canyon rose to the surface about 700 million years ago; the eastern half rose closer to 500 million years ago.

What happened to the Grand Canyon?

The Grand Canyon offers one of the most visible examples of a worldwide geological phenomenon known as the Great Unconformity, in which 250 million-year-old rock strata lie back-to-back with 1.2 billion-year-old rocks. What happened during the hundreds of millions of years between remains largely a mystery. Grand Canyon National Park
