Concentration mechanisms of hydrothermal precious metals on the modern marine seafloor and ancient analogues
Titel
Concentration mechanisms of hydrothermal precious metals on the modern marine seafloor and ancient analogues
Kurzbeschreibung
In the marine environment, precious metals of high economic importance (e.g. Au, Ag, Pd and Pt) occur up to ore-grade level in modern seafloor magmatic hydrothermal systems. This research project aims the investigation of depositional mechanisms that lead to the concentration of precious metal on the modern seafloor. A combination of high-resolution scanning and transmission electron microscopy coupled with in-situ chemical techniques will be applied on samples from a range of seafloor magmatic-hydrothermal systems with significant output of magmatic volatiles. New insights on the submarine ore-formation on a micro/nano scale will be provided, which yield information about the nature of precipitated metals and supports the evaluation of the economic potential of future marine ore deposits.
