Noted for trap rock quarries which provided stone for construction purposes. See also "West Paterson." Historically, many Paterson specimens were mistakenly labeled "West Paterson", because the trolley stop used by collectors taking public transportation stopped at the conveniently located "West Paterson Station".

This geological map and associated information on rock units at or nearby to the coordinates given for this locality is based on relatively small scale geological maps provided by various national Geological Surveys. This does not necessarily represent the complete geology at this locality but it gives a background for the region in which it is found.

|Late Jurassic - Early Jurassic|
145 - 201.3 Ma
|Passaic Formation Conglomerate and Sandstone facies|
Age: Jurassic (145 - 201.3 Ma)
Stratigraphic Name: Passaic Formation
Description: Conglomeratic sandstone (JTrpsc) is brownish-red pebble conglomerate, medium- to coarse-grained, feldspathic sandstone and micaceous siltstone; unit is planar to low-angle trough cross laminated, burrowed, and contains local pebble layers. Unit forms upward-fining sequences 0.5 to 2.5 m (1.6-8 ft) thick. Conglomeratic sandstone thickness exceeds 800 m (2,625 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.
