My research is centred around the processes and consequences of fluid-solid interactions. Parts of my research aim at addressing purely scientific questions while others are relevant for the minerals and resources industry. I use a cross-disciplinary research approach integrating experimental techniques, numerical modeling, and textural characterization and analysis - inspired by fluid-solid interactions in natural laboratories. My current fundamental research focusses on timescales and processes of reactive fluid flow and mass transport through the oceanic and continental crust, while my applied research is geared towards defining footprints of economically significant mineral deposits and metal liberation (Li, Cu, Ni) by hydrometallurgical techniques.

Deciphering recharge of the deep long-term carbon cycle

This is an ongoing research project in the Linnajavri area of northern Norway. The project builds upon previous fieldwork in the area and is focused on large-scale devolatilization textures, suggesting release of C-bearing aqueous fluid at relatively low metamorphic conditions. We are interpreting the reactions observed as representative for those anticipated during subduction of carbonate-bearing oceanic lithosphere. Collaboration with O. Plümper (Utrecht University, NL).

Understanding fluid-rock interactions and lixiviant/oxidant behaviour for the in-situ recovery of metals from deep ore bodies

Experimental project in collaboration with CSIRO and Curtin University investigating a variety of lixiviant/oxidant systems under a range of temperatures and pressures expected to occur in a mineralised in-situ leaching environment. The study is aimed at understanding the interaction between the fluid and Cu-sulphide (chalcopyrite/bornite) with a focus on the reaction mechanisms, mineral dissolution rates and secondary mineral formation.

The laboratory offers a wide range of experimental equipment to investigate mineral replacement and dissolution reactions at conditions ranging from Earth surface weathering to deep-crustal hydrothermal, in rock- and fluid-dominated, open and closed systems. The integrated post-experimental analysis of recovered fluid and solid samples is conducted in collaboration with LabELISA, ELMILAB, and through external research collaborations. The current research focus lies on metal release and transport, CO2 sequestration, and feedback mechanisms between coupled reactions.  

  • Continuous-flow hydrothermal reactor

PARR Instruments™ custom-built hydrothermal reactor capable of continuous-flow hydrothermal fluid-solid experiments up to conditions of 400˚C and 400 bar. All wetted parts are built from C276 and Ta-coated T316, thus offering strong resistance to corrosion. The fluid-delivery system comprises a VINDUM VP-6K-HC High-Pressure Metering Pump (flow rate: 0.00002 – 54 ml/min) and a SFC-24 supercritical CO2 pump. CO2 dissolution is achieved in a stirred 250 mL water-cooled high-pressure mixing reactor. Continuous logging of pressure and temperature data from three thermocouples and two pressure transducers, as well as up- and downstream fluid sampling ports allow for complete monitoring of reaction parameters. A DEGASi 6-channel degasser system has been added for hydrothermal flow experiments at low fO2 conditions relevant for deep-crustal fluid flow systems.

  • Compact stirred high-pressure reactors

Two series 5500 HP Stirred Compact Reactors (PARR Instruments™) offer closed system hydrothermal fluid-rock interaction experimental capabilities up to 350 ˚C and 200 bar. Wetted parts (dip tube, stirrer, thermocouple, liner) are composed of grade-2 titanium. The reactors are equipped with liquid and gas sampling ports connected to a 1 mL Vici sampling loop. An additional gas-inlet port allows for experiments in e.g., N2 or Ar atmospheres and closed-system carbonation experiments.

  • Closed system acid digestion vessels

Closed system vessels represent the simplest hydrothermal reactors but nevertheless offer exciting capabilities for large-scale screening and time-series experiments. The vessels are fitted with PTFE liners (Tmax: 220˚C) with few additional PPL liners (Tmax: 280˚C) for higher temperature experiments at vapor pressure. Three VWR forced convection ovens allow for simultaneous experiments at three different temperatures, one of which is equipped with a custom-built N2-purged vacuum chamber for experiments in O2-free atmosphere.
