Hydrothermal processes along mid-ocean ridges
Sabina Strmic Palinkas
Hydrothermal vents along mid-ocean ridges are locations of an intensive ore-forming activity and represent ideal sites to study modern analogues of ancient volcanogenic massive sulphide (VMS) deposits. The main goal of the project is to get better insight into recent hydrothermal processes, combing fluid inclusion studies with mineral chemistry, stable isotopes and thermodynamic modelling, and to apply gained knowledge to explore and better understand onshore VMS deposits as important sources of numerous critical metals, including metals essential for green energy technologies.
The project is funded by Equinor Akademiaavtale.

Fluid inclusion and melt inclusion lab at Department of Geosciences
The fluid inclusion laboratory at the Department of Geosciences, UiT, is equipped with a Linkam THMS600 heating-freezing stage and with a Linkam TS1400XY heating stage. The facilities allow studies of fluid and melt inclusions in a temperature range from -180 up to +1300°C.
In collaboration with the Department of Physics and Technology, we have purchased a confocal Renishaw micro-Raman system for determination of volatiles and solid phases entrapped in fluid and melt inclusions. The system shall be set up by the end of 2020.
Our expertise covers a broad range of magmatic-hydrothermal and hydrothermal mineral deposits, including porphyry Cu-Au deposits, base metals skarns, Carlin-like deposits, epithermal Au deposits, VMS and recent submarine hydrothermal deposits, as well as in pegmatites.
At the Department of Geosciences we also have the sample preparation equipment for complete preparation of double-polished fluid and melt inclusion wafers.
