Structural and Petrological Study of the Klemetsaunet Plagiogranite, Trondheim, Norway
The Klemetsaunet plagiogranite is a felsic rock connected with the Bymarka ophiolite, and is a part of the Upper allochton of the Scandinavian Caledonides. The plagiogranitic body is cut by several mafic dikes, and this thesis provides a detailed map of the local lithologies.
The plagiogranite has porphyroblasts of garnet and hornblende that are showing syn-tectonic features. The mafic dikes have individual mineralogies, likely due to local events.
Through X-Ray Diffraction (XRD) and X-Ray Fluorescence (XRF) analyses, characteristic elements for ocean floor metamorphism are examined. The results are inconclusive, but show that regional metamorphism most likely have played a more important role than ocean floor metamorphism for the rocks in the area.
