1. Cr-spinels in the Franklinian Mobile Belt : a geochemical record of Paleozoic tectonics
Kandidat-uppsats, Stockholms universitet/Institutionen för geologiska vetenskaperSammanfattning : The chemical compositions of Cr-spinel extracted from mafic and ultramafic rocks collected on Ellesmere Island in the Arctic Canadian Archipelago were obtained through electron microprobe analyses. The extensively altered rocks are sampled from rock units in the Franklinian MobileBelt, which is representative of a Paleozoic tectonically active oceanic regime of which little is presently known.

2. Compositional Systematics of Sphalerites from Western Bergslagen, Sweden
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Sphalerite is, apart from being the main global source of zinc (Zn), also one of the main source for the critical elements indium (In), gallium (Ga) and germanium (Ge), which can be extracted as by-products during Zn mining. In the westernmost part of the Palaeoproterozoic Bergslagen ore province, Sweden, In-anomalies have been reported from sulphide mineralizations. LÄS MER
