...FREDERICK WALKER Abstract The Palisade diabase sill of New Jersey has been widely cited as a type case of gravitational differentiation, and the present investigation is an attempt to explain certain inconsistencies which appear in previous accounts and to make them completely convincing. New data...

...Alan I. Benimoff; Charles B. Sclar Abstract In the Palisades Sill on Staten Island, New York, is an extraordinary example of two coexisting chemically divergent magmatic liquids, now represented by the diabase of the Palisades sill and a pyroxene trondhjemite derived by fusion of the margins...

... The Upper Nyack (UN) section of the Palisades sill is comprised principally of pigeonite-augite and augite diabases with an interstitial (remnant) glassy mesostasis. Major- and trace-metal analyses of 110 diabases, 20 being analyzed for rare-earth elements (REE), provide data regarding...

The Palisades System includes 16 additional early Jurassic diabase intrusive sills or sheets in the Newark Basin exposed west...

..., and water, magnesia, silica, iron, zinc, and sulphur were brought into the dolomite. However, the magnesia and silica were probably not magmatic in origin. Judging from published accounts, the Palisades diabase of New Jersey and New York, like the Safe Harbor diabase, metamorphosed its wall rock under...

... of the magma is estimated from the composition of the border facies. It is very similar to the Bushveld complex. It is a basaltic magma, just saturated, and is comparatively low in TiO 2 , Fe 2 O 3 , and K 2 O. Otherwise it is much like the Karroo dolerites or Palisades diabase. An estimate of the composition...
