continental crust

The average age of the current Earth's continental crust has been estimated to be about 2.0 billion years.

In contrast, the bulk of the continental crust is much older.

Granite is currently known only on Earth, where it forms a major part of continental crust.

Such old continental crust and the mantle below it are less dense than other places in the earth.

This means that oceans and continental crust existed within 150 million years of Earth's formation.

Research interests: Origin, development, and structural evolution of the continental crust.

This oceanic material appears to have been thrust upon the continental crust.

This is the beginning of the continental crust subsidence.

About 40% of the Earth's surface is now overlaid by continental crust.

Thus the continental crust is normally much thicker under mountains, compared to lower lying areas.

The timeline of continental crust exposure is too vague for the correlation to be a home run.

As we have already seen, continental crust is too light to sink down into the mantle with the descending plate.

Some areas of continental crust are largely covered by the sea and may be considered submerged continents.

The under-ocean part constitutes about 20% of the continental crust.

The process starts with heating at the base of the continental crust which causes it to become more plastic and less dense.

The oceanic crust of the sheet is different from its continental crust.

The continental crust has an average composition similar to that of andesite.

The generation and evolution of the continental crust.

So most likely plate tectonics have been with life from the start, and so has continental crust.

The Taiwan Strait off the south coast is actually continental crust beneath.

The earlier notion that the lower continental crust is largely basaltic in composition has received little support from more recent studies.

A plate can contain both oceanic and continental crusts.

They also found that the oceanic crust was much thinner than continental crust.

The continental crust is by contrast typically magnetically quiet.

On average the upper continental crust has the same composition as granodiorite.
