... 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...

... associated Lower Jurassic intrusives. 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...

... cut into the relatively soft mudstones. Stratigraphically from bottom to top, the three ridges are known as the First, Second, and Third Watchung Mountains and average 183, 229, and 91 m thick, respectively (Faust, 1975). A fourth basalt ridge located west of the Third Watchung was recognized by Black...

... and Second Watchung-York Haven suite and the Quarryville basalts of Pennsylvania and New Jersey. The Moroccan Meseta of western and central Morocco consists of Lower Jurassic (Liassic) evaporites intercalated with low-alkali quartz tholeiites, yielding an isotopic mean age of 186 ± 8 m.y. This tholeiite...

...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...

The second magma extruded as a highly fractionated 150-m-thick Preakness basalt flow and crystallized as a central layer of Palisades diabase of similar composition. Subsequent...

These are part of the group D lavas of Alona Bay and the compositionally identical group 3b lavas at Mica Bay (Fig.  5 c ; Table  2 ; Klewin and Berg 1990 , 1991...

The Woman was surrounded by about 10 000 basalt cobbles transported from many miles away and used to hammer pieces of metal (including the ‘head’: Peary 1898 , p. 146; Buchwald...
