Marine Mineral Resources are metal deposits in the oceans that may become of economic relevance in the near future. The research of the MMR group at GEOMAR focuses on the understanding of ore forming processes, geological exploration of the seafloor and estimating the resource potentials (and where we potentially find marine mineral deposits). The focus of our research are polymetallic massive sulfides and porphyry and epithermal copper-gold deposits. We are using a 'source-to-sink' approach in order to understand all aspects that contribute to the formation of metal deposits at the seafloor.
