Fe-Ti mines and prospect in the Egersund are of the South Rogaland Igneous Province. Field report 1995.

The current report summarize the summer of 1995 field work in the Sokndal area of the South Rogaland igneous province. It also provides some preliminary results on petrography. The field work was focused on revisiting and sampling of known Fe-Ti mines and prospect and Fe-Ti carrying plutons in the province. Much attention has been concentrated on deposits related to the Bjerkreim- Sokndal intrusion (the Mydland and Sokndal lobes) due to the proximity of the Tellnes plant and the possibility of deriving high quality (low C) ilmenite from oxide rich zones in the layered complex. The Storgang dyke and, to lesser extent, the Blåfjell-Måkevatn pegmatite have been samples and investigated in detail. Storgangen was emplaced as a layered sill and subsequently deformed by inter-plutonic movements. The Bøstølen layered series, various noritic, oxidic and ilmeno-anorthositic dykes and lenses found within the Åna-Sira anorthosite have been sampled and described. Occurrences belonging to the Lakssvelefjell- Koldal sheet in the western part of the Egersund province is briefly commented on.
