Topics include geological mapping, sub-bottom profiling of local bays or lakes, and investigation of the relationship between landforms and surface processes. Includes a weekend field trip. Mineral chemistry and crystallography are explored through hand specimen identification, optical microscopy, scanning electron microscopy, energy dispersive spectrometry, and phase diagrams. Emphasis is placed on mineral associations, and on the genesis of minerals in igneous and metamorphic rocks. Survey of earth's depositional systems, both continental and marine, with emphasis on241a.
Geologic structures yield evidence for the dynamic deformation of the earth's crust.
This course examines deformation at scales that range from the plate-tectonic scale of the Appalachian mountains to the microscopic scale of individual minerals. A strong field component provides ample opportunity for describing and mapping faults, folds, and other structures exposed along the Maine coast. Geology 101 or 200, or permission of the instructor. Marine Geology and Tectonics. The geological and geophysical bases of the plate-tectonics model.
