The Gondwana supercontinent underwent a 60-degree rotation across Earth's surface during the Early Cambrian period, according to new evidence uncovered by a team of Yale University geologists. Gondwana made up the southern half of Pangaea, the giant supercontinent that constituted the Earth's landmass before it broke up into the separate continents we see today. The study, which appears in the August issue of the journal Geology, has implications for the environmental conditions that existed...

Princeton University scientists have shown that, in ancient times, the Earth's magnetic field was structured like the two-pole model of today, suggesting that the methods geoscientists use to reconstruct the geography of early land masses on the globe are accurate. The findings may lead to a better understanding of historical continental movement, which relates to changes in climate. By taking a closer look at the 1.1 billion-year-old volcanic rocks on the north shore of Lake Superior, the...

Tiny organisms that covered the planet more than 250 million years ago appear to be a species of ancient fungus that thrived in dead wood, according to new research published October 1 in the journal Geology. The researchers behind the study, from Imperial College London and other universities in the UK, USA and The Netherlands, believe that the organisms were able to thrive during this period because the world's forests had been wiped out. This would explain how the organisms, which are...

Billions of years of history have been uncovered with a new technique that is helping scientists paint a picture of how Earth's continents were arranged. Scientists are using the new method to recover rare minerals from rocks and analyze their composition. In addition, researchers claim they can accurately date ancient volcanic rocks for the first time. The early landmasses can be pieced together by aligning rocks that have a similar age and orientation. Scientists say the new approach will...

Two giant plumes of hot rock deep within the earth are linked to the plate motions that shape the continents, researchers have found. The two superplumes, one beneath Hawaii and the other beneath Africa, have likely existed for at least 200 million years, explained Wendy Panero, assistant professor of earth sciences at Ohio State University. The giant plumes -- or "superpiles" as Panero calls them -- rise from the bottom of Earth's mantle, just above our planet's core. Each is larger than the...

By Steve Kuchera, Duluth News-Tribune, Minn. Aug. 7--IT DOESN'T LOOK EXTRAORDINARY -- but a rock found in Antarctica by a University of Minnesota Duluth professor is helping researchers reconstruct what a supercontinent that existed a billion years ago looked like. Analysis of the chunk of granite collected by UMD geology professor John Goodge in 2005 indicate that part of Antarctica and North America were joined 1.4 billion years ago. "We got really lucky -- I had no idea what we were...

In a paper published in this month's "ËœGeophysical Journal International', Dr Graeme Eagles from the Earth Sciences Department at Royal Holloway, University of London, reveals how one of the largest continents ever to exist met its demise.Gondwana was a "Ëœsupercontinent' that existed between 500 and 180 million years ago. For the past four decades, geologists have debated how Gondwana eventually broke up, developing a multitude of scenarios which can be loosely grouped...
