Structure and correlation of Newark trap rocks of New Jersey
Summary In addition to the structures and relations heretofore recognized, the following conclusions are presented in this paper: (1) That the trap of Second Watchung mountain is a double flow, separated locally by sediments deposited on a warped surface. (2) That there was further local depression, with corresponding thickening of sediments, in the interval between the Second Mountain flows and that of Long hill. (3) The crescentic trap ridge of New Vernon is definitely correlated with that of Long hill. (4) The small extrusive remnants at Sand Brook and New Germantown are regarded as probably identical, or at least contemporaneous, with the First and Second Mountain sheets. (5) The hypothesis of a feeding dike along the western flank of the Palisades is regarded as highly improbable. (6) The continuity of the Palisades sill with the Rocky Hill trap, suggested by several former observers, is practically established by data from deep . . .
