Copper Chains: Earth’s Deep-Seated Hold On Copper Revealed. Earth is clingy when it comes to copper. A new Rice University study recently published in the journal Science finds that nature conspires at scales both large and small — from the realms of tectonic plates down to molecular bonds — to keep most of Earth’s copper buried dozens of miles below ground.
This garnet pyroxenite xenolith from Sierra Nevada, Calif., is an example of the deepest products of crystallization within the magmatic belts of subduction zones. Rice University’s Cin-Ty Lee and colleagues showed that most of the copper in arc magmas eventually end up in these deep-seated rocks. Read more here.
