...-TiO 2 quartz normative, and (4) high-Fe 2 O 3 quartz normative. The determination of just where the Watchung Basalt fits into this classification scheme, together with its genetic implications, is a major objective of this paper. We also describe how the structural changes that occurred during...

... Field observations of Early Jurassic Watchung Basalt throughout the Watchung syncline, including 17 large trap-rock quarries, provide new data on the number of flows, their structure, and the eruptive style of the lavas. Three Orange Mountain Basalt flows, five Preakness Basalt flows, and two...

... of the Newark Basin of New Jersey (the First, Second, and Third Watchung Basalts). Our geochemical data impose some constraints on any time-stratigraphic correlation of the basalts in the two basins. We suggest that the Holyoke and Second Watchung Basalts are fractionation products of a Talcott-First Watchung...

The intermediate volcanic sequence, including the Deerfield basalt, the Holyoke basalt, and the base of the Second Watchung basalt, yields anomalous directions that differ by more than 30° from the nominal Early Jurassic direction. These anomalous directions record...

... specimens may have been found in the Paterson region before. Thus, in the F. A. Canfield collection there is, as noted by Mr. A. C. Bates, 1 “a fine specimen of well-formed quartz crystals turned into pectolite.” Dr. Fenner, in his paper on the Watchung basalt and the paragenesis of its zeolites 2 mentions...

Figure 2.  Stratigraphy of the Triassic and Jurassic rocks of the Newark Basin, New Jersey and New York. The Orange Mountain, Preakness, and Hook Mountain basalts are referred to by Olsen ( 1980 ) as the basalt formations of the Newark Basin but are informally known as the Watchung basalts.

...John H. Puffer; Richard A. Volkert Abstract Coarse-grained segregations are found in several subaerial flows of Jurassic flood basalts in the Watchung Mountains, New Jersey. They are particularly common within a 140–180-m-thick quartz-tholeiitic Preakness flow, the thickest of the Watchung flows...

.... For comparison, we present new age determinations of the benchmark Watchung flows I and III of the Newark basin: 201.0 ± 2.1 and 198.8 ± 2.0 Ma, respectively. Collectively, these data suggest that basaltic volcanism responsible for the dikes, flows, and sills of eastern North America occurred within ∼1 m.y...

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...
