Passaic Formation Conglomerate and Sandstone facies (NJJTRpsc;5)

State	New Jersey
Name	Passaic Formation Conglomerate and Sandstone facies
Geologic age	Lower Jurassic and Upper Triassic
Original map label	JTrpsc
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.
Primary rock type	conglomerate
Secondary rock type	sandstone
Other rock types	siltstone
Lithologic constituents	Major Sedimentary > Clastic > Mixed-clastic > Conglomerate-sandstone (Bed)brownish-red pebble conglomerate, medium- to coarse-grained, feldspathic sandstone; unit is planar to low-angle trough cross laminated, burrowed, and contains local pebble layers. Conglomeratic sandstone thickness exceeds 800 m (2,625 ft). Minor Sedimentary > Clastic > Siltstone (Bed)micaceous siltstone; unit is planar to low-angle trough cross laminated, burrowed, and contains local pebble layers. Sedimentary > Clastic > Sandstone (Bed)medium- to coarse-grained, feldspathic sandstone; unit is planar to low-angle trough cross laminated, burrowed, and contains local pebble layers.
