Llandovery 433.4 - 443.8 Ma ID: 2943467 | Lower part of Rangeley Formation Age: Llandovery (433.4 - 443.8 Ma) Stratigraphic Name: Rangeley Formation Description: Gray, thinly laminated (5-25 mm) metapelite with local lentils of turbidites and thin quartz conglomerates in western New Hampshire. Sparse calc-silicate pods and coticule. Probably equivalent to member B of Rangeley Formation of Maine. Comments: Part of the Central Maine Composite Terrane (Central Maine Trough) - Variably metamorphosed sedimentary and volcanic rocks of greenschist to granulite facies, locally migmatized. Area includes structural belts between the Monroe fault on the west and the Campbell Hill fault on the east; that is, the Bronson Hill anticlinorium, Piedmont allochthon, Kearsarge-central Maine synclinorium, central New Hampshire anticlinorium, and Rochester-Lebanon (Maine) antiformal synclinorium. Granite sill, Gilmanton quadrangle (point within formation): 359+/-? U/Pb, monazite per NH030. Granite pegmatite, Suncook quadrangle (point within formation) 375+/-? U/Pb per NH030.
