Abstract (Swedish)
I denna uppsats undersöks granitiskt material från trakten av Örnsköldsvik. Det rör sig om så kallade sensvekofenniska graniter i den Bottniska bassängen. Syftet är att se om det finns något samband mellan materialets beskaffenhet och hur djupt ned i jordskorpan det trängt in. Materialet har undersökts i optiskt mikroskop. Resultaten antyder att det kan finnas skillnader som svarar mot djupet men det går inte att dra några säkra slutsatser. Detta skulle kräva ett betydligt större material. Kompletterande undersökningar har gjorts i elektronmikroskop. Bland annat undersöktes vad som såg ut att vara radioaktiva skador. Denna misstanke bekräftades.
Abstract
Here I present results from an investigation of granitic material from the area of Örnsköldsvik in east central Sweden, late Svecofennian granites in the Bothnian basin. The aim of the study was to see if there is any difference between the features of the material from different depths of intrusion. The results from light microscopy indicate that such might be the case, but the material is far too small for this investigation to settle the question. Analyses were also performed by electron microscopy, among other things on what appeared to be radioactive damage of the material. This suspicion was confirmed.
