Cauldron subsidence at Mount Desert Island, Maine
Chapman CA and National Park Service, Acadia National Park. 1953. Cauldron subsidence at Mount Desert Island, Maine. Geological Society of America Bulletin. 64:1406-1407
This is written about the placement of granite bodies and suggest the causation being cauldron subsidence. 'It is concluded that the granite bodies were implaced by cauldron subsidence. Evidence supporting this interpretation includes: (1) smooth, rounded contacts; (2) partially preserved arching roof; (3) small screen between the granites; (4) contact shatter zone; (5) tangential granite satellites; (6) tangential pegmatite veins; and (7) centripetal dips in breccia and bedding of slightly disturbed metasediments.' /STUDY LOCATIONS:/ /MOUNT DESERT ISLAND/
