To conclude the geology education, students are required to research a subject and write a paper on it. I have chosen to go underground and explore the Chalmers intrusion in Gothenburg. Trafikkontoret has driven a tram-line tunnel through the hill, which presents an excellent opportunity to see the intrusion in 3D. Specifically, I have looked at the mingling and mixing phenomena between the mafic magma and the felsic gneissic country rock; also researching the age, temperature and pressure of formation. This entailed crushing and grinding of rock samples, frying them in electron microscopes and ion probes, peering at thin sections, and digging through the library for interesting texts.
This work area is divided into four parts, describing the various aspects of a petrogenetic study:
And last but not least, I've got to thank professor David Cornell for seeing me through all this. *applause*
