Zircons reveal the history of fluctuations in the oxidation state of crustal magmatism and the supercontinent cycle

Zircons, a mineral nearly as old as Earth itself, crystalize when magmas (molten rocks) cool and can be found in trace quantities in magmatic rocks. The formation of magma constitutes the mountains on the Earth. Through interactions ...

Geologists explore the hidden history of Colorado's Spanish Peaks

If you've driven the mostly flat stretch of I-25 in Colorado from Pueblo to Trinidad, you've seen them: the Spanish Peaks, twin mountains that soar into the sky out of nowhere, reaching altitudes of 13,628 and 12,701 feet ...

Mantle convection linked to seaway closure that transformed Earth's oceanographic circulation patterns

Continental drift is a concept familiar to many, referencing the movement of Earth's continents due to shifting tectonic plates over millions of years, splitting one globe-spanning supercontinent into the configuration we ...

Saturday Citations: Einstein revisited (again); Atlantic geological predictions; how the brain handles echoes

Einstein's inexhaustible field equations just keep on predicting weird stellar objects, and the latest one is a doozy—so strap on your helmet, inside of which is another helmet, encasing still yet another helmet. This headgear ...

Why olivine and diamonds are best friends and how that could simplify the search for precious gemstones

Few gemstones are more difficult to find than diamonds. Geologists from ETH Zurich and the University of Melbourne have now established a link between their occurrence and the mineral olivine. This could make the search for ...

New insights into the India–Asia collision in the Western Himalayas dating back to circa 55 million years

Hundreds of millions of years ago, the surface of the Earth looked very different from how we see it today. There were just two continents: Laurasia and Gondwanaland. The present Indian subcontinent was part of Gondwanaland, ...
