Abstract:
Extensive drilling is in progress along the right-of-way of a proposed flood diversion tunnel in northern New Jersey. This 21.8-km tunnel would cut across the strike of the Newark basin in an area where rock exposures are few because of glacial deposition.
Approximately 2,400 m of the 6,300-m thick northern portion of the Newark basin is represented in rock cores. The uppermost 870 m of Upper Triassic strata has been drilled along with 1,620 m of Lower Jurassic strata. The Jurassic strata include the three Watchung Mountain sheet basalts sandwiched between fluvial and lacustrine sedimentary deposits.
What emerges for the first time is a continuous picture of the previously poorly exposed Jurassic lacustrine deposits. These cyclic deposits containing kerogen-rich layers are some of the youngest strata found in Mesozoic rift basins. These westernmost Newark basin deposits can be correlated to similar age deposits in outer continental shelf drill holes and possibly help the wildcat exploration starting to appear in the Newark basin.
