Late Triassic
201.3 - 237 Ma



ID: 2988466
Brunswick Formation

Age: Late Triassic (201.3 - 237 Ma)

Stratigraphic Name: Brunswick Formation

Description: Mudstone, sandstone and arkose.

Comments: part of Newark Group 0-7000 ft. (0-2100 m). Unit description from USGS Lexicon website (ref. NY046) and reference NY045: The rank of the Brunswick is raised to Brunswick Group of the Newark Supergroup in NJ, NY, and PA. It includes the Passaic Formation of Olsen (1980), in NJ and NY, the Orange Mountain Basalt in NJ and NY, the Feltville Formation in NJ, the Preakness Basalt in NJ and NY, and the Towaco Formation, Hook Mountain Basalt, and Boonton Formation in NJ. In PA, the Brunswick Group is divided into the lower part, equivalent to the Passaic, the Jacksonwald Basalt, equivalent to the Orange Mountain, and the upper part, equivalent to the Feltville (Lyttle and Epstein, 1987).
