Using seismic waves, scientists detect widespread partially molten rock hidden under the Earth’s tectonic plates in a new way, a step in settling a long-held geological debate that has big implication...
New research analyzing pieces of the most ancient rocks on the planet adds some of the sharpest evidence yet that Earth’s crust was pushing and pulling in a manner similar to modern plate tectonics at...
A new study co-led by a Cornell researcher has identified serpentinite – a green rock that looks a bit like snakeskin and holds fluids in its mineral structures – as a key driver of the oxygen recycli...

Shocked meteorites provide clues Earth lower mantle
2020/2/20
Deep below Earth's surface lies a thick rocky layer called the mantle, which makes up the majority of our planet's volume. While Earth's mantle is too deep for humans to observe directly, certain mete...
In grade-school science textbooks, Earth's mantle is usually shown in a yellow-to-orange gradient, a nebulously defined layer between the crust and the core.To geologists, the mantle is much more than...

LSU Researchers Minerals Volcanic Rock First 1.5 Billion Years Earth's Evolution
2017/11/23
The first 1.5 billion years of Earth’s evolution is subject to considerable uncertainty due to the lack of any significant rock record prior to four billion years ago and a very limited record until a...

ASU geoscientists puzzling pockets rock deep Earth's mantle
2017/9/1
A team led by geoscientists from Arizona State University and Michigan State University has used computer modeling to explain how pockets of mushy rock accumulate at the boundary between Earth's core ...
More than 550 million years ago, the oceans were teeming with flat, soft-bodied creatures that fed on microbes and algae and could grow as big as bathmats. Today, researchers at the University of Cali...
UMD-led Study Finds Ancient Earth’s Fingerprints in Young Volcanic Rocks
UMD-led Ancient Earth’s Fingerprints Young Volcanic Rocks
2017/4/27
Earth’s mantle is made of solid rock that nonetheless circulates slowly over millions of years. Some geologists assume that this slow circulation would have wiped away any geochemical traces of Earth’...
