Bedrock geology of Mount Desert Island
Chapman CA and National Park Service, Acadia National Park. 1988. Bedrock geology of Mount Desert Island. University of Illinois, Urbana
Briefly summarizes the bedrock geology of Mount Desert Island. Mount Desert Island, the largest bedrock island on our Atlantic coast, lies on a long belt of lower and middle Paleozoic rocks that trends roughly parallel to the Maine coastline. The rocks of this belt were derived principally from magmatic sources over a geologically long period of time (probably Ordovician to Devonian). The older representatives, originally stratified pyroclastic materials and interlayered lava flows, constitute the (1) Ellsworth Schist, (2) Cranberry Island Series, and (3) Bar Harbor Series. The younger representatives, principally gabbroic and granitic intrusive rocks, constitute the (1) Bays-of-Maine igneous complex and (2) Maine coastalplutons. /STUDY LOCATIONS:/ /MOUNT DESERT ISLAND/
