This borehole was drilled as an attempt to drill as deep as possible in the earth's crust. The well, which began drilling in 1970 finished in 1989 at 40,230 feet and is the deepest man-made hole ...

To do so, Dr. Ziyi Zhu, Research Fellow at Monash University, Australia, and colleagues developed a theoretical model for the mass/volume balance of continental crust and compared the amount of ...

The scientists computed with unprecedented precision the amount of landmass, or “continental crust,” before and after the collision. “What we found is that half of the mass that was there 60 million ...

The study, published today in Science, uses laboratory experiments to show that the iron-depleted, oxidized chemistry typical of Earth's continental crust likely did not come from crystallization ...

Continental crust is also much less dense than its oceanic counterpart. In 1962, famed Princeton geologist Harry Hess theorized that the thickness of continental crust had to do with sea level and ...

Earth’s continental crust may have emerged 500 million years earlier than scientists had previously estimated. Pinning down when our planet’s land emerged could help us understand the ...

These nutrients help foster life in the seas; a study published Feb. 11 in the journal Science found that when Earth's continental crust stopped growing for about a billion years during Earth's ...

Continental crust is vital in most of Earth’s natural cycles – it interacts with water and oxygen, forming new weathered products, hosting most metals and biological carbon.

A study published in Nature on 2 April reveals that Earth's first crust, formed about 4.5 billion years ago, probably had chemical features remarkably like today’s continental crust.

Case of Earth's missing continental crust solved: It sank Date: October 5, 2016 Source: University of Chicago Summary: How do you make half the mass of two continents disappear?

These nutrients help foster life in the seas; a study published Feb. 11 in the journal Science found that when Earth's continental crust stopped growing for about a billion years during Earth's ...
