Study reveals structure and origins of glacial polish on Yosemite’s rocks

The glaciers that carved Yosemite Valley left highly polished surfaces on many of the region's rock formations. These smooth, shiny surfaces, known as glacial...

Researcher unearths hottest rock on record

It was a stroke of serendipity that led to Michael Zanetti's discovery of the hottest rock on Earth. In 2011, Zanetti, now a postdoctoral researcher...

For under-Earth exploration, engineers deepen understanding of rock stress

Measuring unobservable forces of nature is not an easy feat, but it can make the difference between life and death in the context of...

Hundred-year-old law on fluid flow overturned by new research

Engineers from Imperial College London have dispelled a 100-year-old scientific law used to describe how fluid flows through rocks. The discovery by researchers from Imperial...

Origins of Cu-Pb-Zn-bearing and W-bearing granites

The Nanling Range of South China is world famous for its widely developed, multiple-aged granitic magmatism and related polymetallic mineralization. Various kinds of granites...

How X-rays helped to solve mystery of floating rocks

It's true—some rocks can float on water for years at a time. And now scientists know how they do it, and what causes them...

Weathering of rocks a poor regulator of global temperatures

A new University of Washington study shows that the textbook understanding of global chemical weathering—in which rocks are dissolved, washed down rivers and eventually...

Types of Rocks

Geologists classify rocks into three major groups: igneous rock, sedimentary rock, and metamorphic rock. Metamorphic Rock forms from other rocks that are changed by...

Earth Sciences student research on metamorphic rock in North China

Miss Jessie Kwan Long-ching, a year-4 undergraduate student in the Department of Earth Sciences, the University of Hong Kong (HKU), has just published a...

Between a rock and a hard place: Biologists unearth sandstone-excavating bees

In the popular nursery story The Three Little Pigs, the prudent porker who builds his house of brick is chided by his pals, who...

Scientists study how to print rocks in 3-D

A new 3-D printing technique being developed at Stanford could one day allow scientists to study rocks from afar, without needing to have actual...

Lasers melt rocks to reveal development of super-Earths and how giant...

New experiments provide insight into how Earth-type planets form when giant asteroids or planetesimals collide and how the interiors of such planets develop. Researchers...

Rocks chart Earth’s recovery from extinction

Scientists have shed light on why life on Earth took millions of years to recover from the greatest mass extinction of all time. The study...

Oldest rocks in Australia unlock secrets of the atmosphere

Research into micro-meteorites, meteorites smaller than 2 millimeters, found in Western Australia have shed new light on the make-up of the ancient Earth's atmosphere. The...

Giant Blobs of Rock, Deep Inside the Earth, Hold Important Clues...

Two massive blob-like structures lie deep within Earth, roughly on opposite sides of the planet. The two structures, each the size of a continent...

Turning CO2 into rock

An international team of scientists have found a potentially viable way to remove anthropogenic (caused or influenced by humans) carbon dioxide emissions from the...

Studying life on the rocks

Much of modern life is deeply impacted by the behavior of ice. Now, new work from a team at Lamont-Doherty Earth Observatory at Columbia University...

Methane-producing microbes in California rocks

Deep in vents on the ocean floor, methane-producing microbes feed off chemical reactions between water and rock. Now evidence of this process has been...

Barium leaches directly from fracked rocks

Dartmouth College researchers are shedding light on the early chemical reactions in the organic sediments that would ultimately become the Marcellus Shale, a major...

Is old rock really as “solid as a rock”

In the course of billions of years continents break up, drift apart, and are pushed back together again. The cores of continents are, however,...
