Climate, life and the movement of continents: New connections

A new study by The University of Texas at Austin has demonstrated a possible link between life on Earth and the movement of continents....

Enhanced views of Earth tectonics

Scientists from Germany's Kiel University and British Antarctic Survey (BAS) have used data from the European Space Agency (ESA), Gravity field and steady-state Ocean...

A wrench in Earth’s engine: Stagnant slabs

Researchers at CU Boulder report that they may have solved a geophysical mystery, pinning down the likely cause of a phenomenon that resembles a...

Plate Tectonics May Have Been Active on Earth Since the Very...

A new study suggests that plate tectonics—a scientific theory that divides the earth into large chunks of crust that move slowly over hot viscous...

Geologists reveal ancient connection between England and France

The British mainland was formed from the collision of not two, but three ancient continental land masses, according to new research. Scientists have for centuries...

Upper Cretaceous trench deposits of the Neo-Tethyan subduction zone

The Jiachala Formation, which was fed largely from the Gangdese arc, has long been considered to comprise syn-collisional foreland-basin deposits based on the reported...

Study finds deep subterranean connection between two Japan volcanoes

Scientists have confirmed for the first time that radical changes of one volcano in southern Japan was the direct result of an erupting volcano...

Scientists propose solution to ‘Gaia puzzle’

Scientists may have solved a long-standing puzzle over why conditions on Earth have remained stable enough for life to evolve over billions of years....

Earth could have supported continental crust, life earlier than thought

The early Earth might have been habitable much earlier than thought, according to new research from a group led by University of Chicago scientists. Counting...

New insight into Earth’s crust, mantle and outer core interactions

A new study by the University of Liverpool, in collaboration with the Universities of Lancaster and Oslo, sheds light on a longstanding question that...

Flow in the asthenosphere drags tectonic plates along

New simulations of Earth's asthenosphere find that convective cycling and pressure-driven flow can sometimes cause the planet's most fluid layer of mantle to move...

Utah fossil reveals global exodus of mammals’ near relatives to major...

A nearly 130-million-year-old fossilized skull found in Utah is an Earth-shattering discovery in one respect. The small fossil is evidence that the super-continental split likely...

Sub-sea rift spills secrets to seismic probe

The first study to spring from a Rice University-led 2013 international expedition to map the sea floor off the coast of Spain has revealed...

Keeping an eye on the soundness of structures

Scientists at Tokyo Institute of Technology (Tokyo Tech) used synthetic-aperture radar data from four different satellites, combined with statistical methods, to determine the structural...

Formation of supercontinents and strength of ocean tides

The cyclic strengthening and weakening of ocean tides over tens of millions of years is likely linked to another, longer cycle: the formation of...

Geologist identifies hidden clues to ancient supercontinents, confirms Pannotia

An Ohio University geologist who first proposed the now-accepted supercontinent cycle theory in the 1980s has rallied to the cause of one of those...

Scientists helping to improve understanding of plate tectonics

Scientists at The Australian National University (ANU) are helping to improve understanding of how rocks in Earth's hot, deep interior enable the motions of...

International ocean drilling expedition obtains unique record of plate tectonic rifting...

Core samples taken during an international ocean drilling expedition are yielding the most high-resolution, extended record of continental rifting ever obtained. A team of researchers...

Continental interiors may not be as tectonically stable as geologists think

A University of Illinois-led team has identified unexpected geophysical signals underneath tectonically stable interiors of South America and Africa. The data suggest that geologic...

Analysis of major earthquakes supports stress reduction assumptions

A comprehensive analysis of 101 major earthquakes around the Pacific ring of fire between 1990 and 2016 shows that most of the aftershock activity...
