Passaic Formation Quatzite-clast Conglomerate facies

Quartzite conglomerate unit (JTrpcq) is reddish-brown pebble conglomerate, pebbly sandstone, and sandstone, in upward-fining sequences 1 to 2 m (3-6 ft) thick. Clasts are subangular to subrounded, quartz and quartzite in sandstone matrix. Sandstone is medium to coarse grained, feldspathic (up to 20 percent feldspar), and locally contains pebble and cobble layers. Conglomerate thickness exceeds 850 m (2,790 ft).

Comments Newark Supergroup, Brunswick Group (Lyttle and Epstein, 1987). The Passaic Formation unit description on the map encompasses multiple units (JTRp, JTRpms, JTRps, JTRpsc, JTRpcq, JTRpcl, and TRpg). The Passaic Formation was split into individual units according to the digital map and the appropriate descriptions were used for each. Names for units are from digital map.
