|Merrimack Group, Berwick Formation, Unnamed member|
Age: Paleozoic (419.2 - 485.4 Ma)
Stratigraphic Name: Berwick Formation
Description: Contains more calc-silicate (15 percent) than does the remainder of the formation (5 percent).
Comments: Part of the Nashoba-Casco-Miramichi Terrane (Merrimack Trough). Secondary unit description from USGS Geologic Names lexicon (ref. NH047): Used as Berwick Formation of Merrimack Group. Consists of purple biotite-feldspar granofels or schist. Contains interbeds of calcsilicate granofels and minor metapelites. Includes Gove Member, mapped separately. Stratigraphic sequence with respect to Eliot Formation is uncertain. Age of all formations in Merrimack Group changed to Ordovician(?) to Silurian(?) based on isotopic age determinations of approx 440 and 420 Ma from detrital zircons from Berwick by J.N. Aleinikoff (oral commun., 1994). Onway tholeiite dike (point within formation) = 177 K/Ar, whole rock per NH042.
