During the period 1969 and 1970, blasting occurred in the First Watchung basalt of Paterson and West Paterson, as Interstate highway 80 was being extended through the region. The construction area was immediately adjacent to the workings of the Lower New Street Quarry. Mineralization was found within the pillow formations of the basalt.

Late Jurassic - Early Jurassic
145 - 201.3 Ma

ID: 2738773
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.
