Geological Investigations in Acadia National Park
Dr. Vollmer returned from a successful field excursion to Acadia National Park. The annual Fall excursion offers students a chance to study excellent exposures of plutonic and intrusive rocks not available locally, and to examine field relationships and how they are represented on geologic maps. While the main focus is on bedrock mapping, structures, and intrusive relationships, students also study recent beach deposits and the glacial history.
Studying the deformational and metamorphic features of the metasedimentary Bar Harbor Formation.
Exposures of the intrusive shatter zone in diorite near an active sea cave.
A short but strenuous climb leads to exposures of the Cadillac Mountain Granite on the Beehive, a glacial roche moutonnée.
