Emerging evidence suggests that plate tectonics, or the recycling of Earth's crust, may have begun much earlier than ...

Tiny minerals are revolutionizing our understanding of geology. Easter Island consists of several extinct volcanoes. The ...

Earth surface is covered with rigid plates that move, crash into each other and dive into the planet's interior. But when did ...

Zircon crystals are like fingerprints holding clues of their source. For example, zircons found in 15 million year old river sediments in Colombia possess a signature like volcanic rocks on the ...

An unexpected find in tiny crystals hints that the Earth's mantle may not quite behave as has been believed for nearly a century.

How could that be? Earth's mantle Chemical analysis of the zircons showed that their composition was more or less the same in all cases. So, they all had to have come from magma of the same ...

When we discuss climate change today, we are mostly concerned with how such change will impact our environment and our lives. We look to the past to help understand climate cycles and how our ...

A new study reconstructs how an ancient North American rift system was uplifted in space and time due to subsequent continent-continent collision.

A highlight of this year’s Céleste collection, for example, is the Iconic Star necklace, set with free-form sky-blue ...

To do this, they turned to tiny, uranium-bearing crystals preserved in lava, called zircons, which are like natural little time capsules. The more time that passes after the crystals form from ...
