Mineralogy
This page in Norwegian The Mineralogical-Geological Museum was started in 1915, and developed soon into a centre of geological and mineralogical science, based on work done by excellent predecessors (e.g. W.C. Brøgger). One of the first directors of the museum was Victor Moritz Goldschmidt (1888-1947), who is internationally recognized as the father of modern inorganic geochemistry. The scientific group is still the leading national centre of mineralogy and geochemistry. The museum's mineral collection is one of the best in Europe, in addition to having large collections of ore, rocks and meteorites. Several of the scientific projects are based on our huge collections, with focus on Norwegian minerals.
Our new high-pressure laboratory gives us opportunities to study mineralogy, petrology and geochemistry in the pressure range 0.4 to 3.5 GPa and temperatures up to 2000oC.
Our ongoing scientific projects:
- Systematic mineralogy and mineral paragnesis related to Norwegian mineral localities (Selbekk)
- Anatexis of contrasting mafic rocks in the presence of a H2O-bearing fluid phase (selbekk)
- Melt-fluid-relationship in granitic systems (Aerts)
- P-T conditions for the migmatites on Nordaustlandet, Svalbard (Selbekk)
- Origin of different ores and mineral deposits, including the Oslo Rift and Svalbard (Segalstad)
- Environmental geochemistry, CO2 and greenhouse gas problems (Segalstad)
- Origin of economic mineral deposits: solubility of platinum group elements in halide melts, related to mafic cumulates in layered intrusions (Aerts)
- High pressure mantle melting and trace element partitioning (Aerts)
- Origin, evolution and dynamics of Earth and the terrestrial planets (Trønnes)
- Melting of peridotitic model composition at 20-25 GPa
- Phase relations, crystallography and mineral physics of minerals near the core-mantle boundary
- Geochemistry of primitive flank zone basalts from Island and Jan Mayen (Trønnes)
