- W111199781 abstract "Tectonostratigraphic sequence within the Coastal Lithotectonic Belt of southwestern Maine include the Merrimack Group (MG), Casco Bay Group (CBG), Falmouth-Brunswick sequence (FBS), and Central Maine sequence (CMS). Formations of FBS (Nehumkeag Pond, Mt. Ararat, Torrey Hill, and Richmond Corner), all west of the Norumbega Fault Zone, constitute a separate sequence unrelated to the Casco Bay Group east of the Fault. The age of these rocks is uncertain. The Mt. Ararat and Nehumkeag Pond Fms. are tentatively correlated with lithically similar parts of the Massabesic Gneiss in New Hampshire, and with the Monson Gneiss in Massachusetts. The Mt. Ararat and Nehumkeag Pond Formations, now no longer correlated with the Cushing Fm. may form a basement to the CMS. The CBG, a package of metamorphosed volcanic and pelitic rocks crops out only east of the Norumbega Fault. Felsic metavolcanic rocks of the Cushing Fm. at the base of the CBG give a 471[+-]3 MA U/Pb age on zircons, indicating a Middle Ordovician age for the base of the CBG. The Sebascodegan Fm., an easterly felspathic and calcareous volcaniclastic facies of the upper part of the Cushing Fm., is correlated with the Bucksport Fm. of southeastern coastal Maine, suggesting a Middle Ordovician agemore » for that formation. The Sebascodegan Fm may be equivalent to the Kittery Formation of the MG. The Macworth Fm. of the CBG is equivalent to the Elliot Fm. of the MG, and the Cape Elizabeth Fm. stratigraphically above the Cushing Fm in the CBG, may be equivalent in part to the Elliot Fm. Units of the CBG above the Cape Elizabeth Fm. are not present to the south in the MG due either to faulting or stratigraphic pinchout.« less" @default.
