Formation of the Alps: Detaching and uplifting, not bulldozing

For a long time, geoscientists have assumed that the Alps were formed when the Adriatic plate from the south collided with the Eurasian plate...

Understanding Earth’s ‘deep-carbon cycle’

New geologic findings about the makeup of the Earth's mantle are helping scientists better understand long-term climate stability and even how seismic waves move...

Japan’s geologic history in question after discovery of metamorphic rock microdiamonds

A collaboration of researchers based in Kumamoto University, Japan have discovered microdiamonds in the Nishisonogi metamorphic rock formation in Nagasaki Prefecture, Japan. Microdiamonds in...

Unearthing evidence for the origins of plate tectonics

Minerals trapped inside tiny crystals that have survived the grinding of the continents over billions of years may help to reveal the origins of...

Plate tectonics goes global

Today, the entire globe is broken up into tectonic plates that are shifting past each other, causing the continents to drift slowly but steadily....

Scientists discover fault system in southeastern Nepal

A newly identified fault system in southeastern Nepal has the potential to cause earthquakes in a densely populated area, according to two University of...

Chance of big San Andreas earthquake increased by Ridgecrest temblors, study...

A new study suggests that last year's Ridgecrest earthquakes increased the chance of a large earthquake on California's San Andreas fault. The study, published in...

A new idea on how Earth’s outer shell first broke into...

The activity of the solid Earth -- for example, volcanoes in Java, earthquakes in Japan, etc -- is well understood within the context of...

Which factors control the height of mountains?

Which forces and mechanisms determine the height of mountains? A group of researchers from Münster and Potsdam has now found a surprising answer: It...

Remixed mantle suggests early start of plate tectonics

New Curtin University research on the remixing of Earth's stratified deep interior suggests that global plate tectonic processes, which played a pivotal role in...

Scientists decipher the role of carbon and the break-up of continents

University of New Mexico (UNM) Professor of Earth and Planetary Sciences, Dr. Tobias Fischer and Syracuse University research fellow (now University of Auckland Lecturer),...

Study finds a (much) earlier birth date for tectonic plates

Yale geophysicists reported that Earth's ever-shifting, underground network of tectonic plates was firmly in place more than 4 billion years ago -- at least...

New clues to deep earthquake mystery

A new understanding of our planet's deepest earthquakes could help unravel one of the most mysterious geophysical processes on Earth. Deep earthquakes -- those at...

Earth’s evolutionary tale, researchers probe materials at deep-Earth conditions

Far below the Earth's surface, about 1,800 miles deep, lies a roiling magmatic region sandwiched between the solid silicate-based mantle and molten iron-rich core:...

The Great Unconformity : A billion years is missing from the...

The geologic record is exactly that: a record. The strata of rock tell scientists about past environments, much like pages in an encyclopedia. Except...

Tectonic plates started shifting earlier than previously thought

An enduring question in geology is when Earth's tectonic plates began pushing and pulling in a process that helped the planet evolve and shaped...

Geologists find lost fragment of ancient continent in Canada’s North

Sifting through diamond exploration samples from Baffin Island, Canadian scientists have identified a new remnant of the North Atlantic craton—an ancient part of Earth's...

Building blocks for life on Earth arrived much later than we...

Ancient rocks from Greenland have shown that the elements necessary for the evolution of life did not come to Earth until very late in...

Geologists determine early Earth was a ‘water world’ by studying exposed...

The Earth of 3.2 billion years ago was a "water world" of submerged continents, geologists say after analyzing oxygen isotope data from ancient ocean...

New pieces of evidence found in the Alborán Sea possibly related...

Under the waters of the eastern Alborán Sea and buried at the shadow of an old volcanic edifice lies a body of sediments that...
