"--- --- IMPORTANT GEOLOGICAL FEATURES AND LOCALITIES OF MAINE Dabney W. Caldwell Department of Geology Boston University Introduction The Maine Critical Areas Program and the Maine Geological Survey are compiling a list of the geologic topics and localities of Maine considered significant or unusual enough for further research and possible inclusion in the list of Maine's Critical Areas. To qualify for further study the geologic feature must have significant scientific or educational value.· In addition, the geologic feature should either be unique to Maine or New England or be an outstanding example of a particular geologic phenomenon or feature. In February, 1981, members of the geologic community of Maine were polled for geologic topics that were of interest to them. The compiled results of the 1981 questionnaire were recirculated in early 1982 for further comments from the geologists who live or work in Maine. -

Plate Tectonics Passport
What is plate tectonics? The Earth is made up of four layers: inner core, outer core, mantle and crust (the outermost layer where we are!). The Earth’s crust is made up of oceanic crust and continental crust. The crust and uppermost part of the mantle are broken up into pieces called plates, which slowly move around on top of the rest of the mantle. The meeting points between the plates are called plate boundaries and there are three main types: Divergent boundaries (constructive) are where plates are moving away from each other. New crust is created between the two plates. Convergent boundaries (destructive) are where plates are moving towards each other. Old crust is either dragged down into the mantle at a subduction zone or pushed upwards to form mountain ranges. Transform boundaries (conservative) are where are plates are moving past each other. Can you find an example of each type of tectonic plate boundary on the map? Divergent boundary: Convergent boundary: Transform boundary: What do you notice about the location of most of the Earth’s volcanoes? P.1 Iceland Iceland lies on the Mid Atlantic Ridge, a divergent plate boundary where the North American Plate and the Eurasian Plate are moving away from each other. As the plates pull apart, molten rock or magma rises up and erupts as lava creating new ocean crust. Volcanic activity formed the island about 16 million years ago and volcanoes continue to form, erupt and shape Iceland’s landscape today. The island is covered with more than 100 volcanoes - some are extinct, but about 30 are currently active. -

ABSTRACT The Liberty-Orrington fault separates two tectonic terranes of widely different lithologies and metamorphic grades within the Coastal Lithotectonic Belt of Maine. While the juxtaposition of the sillimanite-bearing Passagassawakeag gneiss and the chlorite grade Bucksport Formation (turbidites) requires a fault between them, field evidence for, and an understanding of, the nature of the fault has hitherto been lacking. Although the Liberty-Orrington fault has previously been interpreted as a thrust, strike- slip, and/or normal fault, the most recent debate has been centered around two models of Acadian amalgamation involving thrusting of the Passagassawakeag terrane from the southeast vs. thrusting from beneath central Maine (from the northwest) (Osberg et al., 1998; Stewart et al., 1995).
