Geology of Maine
Maine's geologic history is characterized by a series of mountain-building events and continental collisions, beginning over 1 billion years ago. The state's bedrock is comprised primarily of metamorphic and igneous rocks, formed during the Precambrian and Paleozoic eras.
Throughout the Paleozoic Era, Maine experienced multiple orogenies, including the Taconic, Acadian, and Alleghenian, which resulted in the formation of the Appalachian Mountains. During the Ice Age, the state was covered by glaciers, which carved its coastline and left behind numerous glacial features, such as moraines and drumlins.
