Do microbes control the formation of giant copper deposits?

[EN] The formation of secondary copper deposits, the source of more than half of the world's production, is usually interpreted as abiogenic. In this study of the Las Cruces deposit (southwestern Spain), in situ hybridization and scanning electron microscopy analysis together with integrated ge...
