Tracing Oxidizing Slab Fluids in Cold Volcanic Arcs

by Susanne Straub 28 October 202215 November 2022

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.

A copper mine delves deep into the orange rock of an Arizona desert. More than a dozen even steps have been excavated leading down to a roughly circular depression in the ground. Some of the steps have patches of oxidized copper, a blue-green color. A smooth path large enough for heavy machinery spirals down into the bottom of the mine.

For Some Copper Deposits, Microbes Make Minable Minerals

by H. Gavin 10 April 201914 February 2023

Copper ores were long thought to form through purely chemical processes, but a recent study provides the strongest evidence yet that microbial metabolism drives mineral production.
