Tracing Oxidizing Slab Fluids in Cold Volcanic Arcs
Elevated copper isotope ratios in arc magmas from fluid-rich cold subduction zones support the role of oxidizing fluids from the subducted lithospheric serpentinite in the oxidization of arc magmas.

What is the Best Predictor of Landfalling Hurricane Damage?
A new study finds that the minimum sea level pressure, as another measure of hurricane strength, is a better predictor of hurricane damage in the United States than the maximum sustained wind speed.

Why is the North China Craton Vulnerable to Destruction?
A new study suggests that carbonatite metasomatism, not silicate metasomatism as previously thought, was dominant prior to the removal of the North China Craton in the early Cretaceous.
