Carbonate rock chemical weathering carbon sinks reduce the rate of increase of the atmospheric CO 2 concentration and global warming. Based on the river ion concentration data, the stochastic forest ...

The discovery by the Mars rovers of carbonate in sedimentary rock on the Red Planet has enabled planetary scientists to rewind the clock and tell the tale of how Mars' warmer, watery climate 3.5 ...

CNOOC made 'the first major exploration breakthrough in ultra-deepwater carbonate rocks offshore China' after drilling about 9,850 feet deep into the Pearl River Mouth Basin. CNOOC Ltd. announced ...

The Curiosity rover was sent up the Mount Sharp, the biggest sediments stack on Mars. On the way, it collected samples that indicated a portion of carbon dioxide in the Martian atmosphere might have ...

Earth has gone through many geologic phases, but it did have one striking period of stasis: Our planet experienced a tropical environment where algae and single-celled organisms flourished for almost ...

One of the great unsolved problems in modern planetary science is written on the surface of Mars. Mars has canyons that were carved by rivers, so it was once warm enough for liquid water. How—and ...
