Abstract

The Newark basin is one of the most accessible and most studied rifts in the world. The principle objective of this project is the recovery, with continuous core, at the entire approximately 6-km-thick Late Triassic age section spanning the stratigraphic interval from the base of the Early Jurassic age basalt flows to metamorphic Paleozoic and Precambrian basement in New Jersey. What will be gained from the coring is a high-resolution chronostratigraphy of the Newark rift basin, which will include production of a detailed Milankovitch-type cyclostratigraphy at the 20 000-yr level. This detailed record will allow most of exposed portions of the basin to be correlated at the same scale of resolution, provide a basis for developing and testing quantitative models of rift basin evolution, and be the basis of a standard biostratigraphic, and geomagnetic reversal time scale for the Late Triassic. -from Authors
