Summary:

Coarse fluvial sediments consisting of a lower white and gray arkose member with basal conglomerate bed and an upper pink arkose and red feldspathic sandstone member are named New Haven Arkose of the Newark Group in Conn. It includes all the sediments underlying the lower lava sheet of the Meriden Formation. Overlies older gneiss and schist. Thickness is 5,000 ft (1,500 m) near Meriden and 9,000 ft (2,700 m) near New Haven where the beds may be repeated by faulting. Age is Late Triassic.

Summary:

New Haven Arkose of the Newark Group is here accepted for use by the U.S. Geological Survey. It unconformably overlies older crystalline rocks and conformably underlies the Talcott Basalt.

Summary:

The New Haven Arkose is extended from north central Connecticut to west central Massachusetts where it is assigned to rocks mapped by Emerson (1898) as Longmeadow Sandstone and Sugarloaf Arkose.

Summary:

Used as New Haven Arkose of Late Triassic and Early Jurassic age. The Late Triassic-Early Jurassic boundary is arbitrarily drawn through clastic rocks of similar lithology below a Lower Jurassic palynofloral zone in gray mudstone in the uppermost part of the New Haven. The New Haven is continuous with and lithologically similar to the Sugarloaf Formation in the Deerfield basin. In Massachusetts the New Haven underlies the Shuttle Meadow Formation. The Hitchcock Volcanics at Mount Hitchcock is intrusive into arkose of the New Haven.

Summary:

The New Haven Arkose of the Newark Supergroup is mapped in the Hartford and Pomperaug basins, where it underlies the Talcott Basalt or, where the Talcott pinches out to the north, the Shuttle Meadow Formation. Age is Late Triassic.
