Class Details

Using plate tectonics and the geologic assembly of New England as a template, this course explores the origin of crystalline rocks – volcanic, plutonic, and metamorphic – that comprise 94% of the earth’s crust and record most of its history. Field and lab studies (the crux of the course) are backed up by phase-rule applications and fundamental thermodynamic principles. Chemical and mineralogical compositions and rock fabrics provide evidence for crystallization or re-crystallization processes and environments, particularly as they define present or past plate boundaries or tectonic settings. Lab work emphasizes thin section analysis, with a 3-week segment devoted to interpreting the igneous rocks of New England collected on field trips..
