Abstract
A one-dimensional conductive thermal model is used to calculate the transient thermal history of the Newark basin. A burial and erosion history for the Newark basin is constructed for the modeling, including changes in heat flow through time, emplacement of Jurassic lava flows at the surface, and emplacement of the Palisades sill at depth. Vitrinite-reflectance values and apatite and zircon fission-track ages, for units of both Triassic and Jurassic age, are used to constrain the models. Modeling results indicate that initial formation of the Newark basin is not coincident in time with a thermal event. Elevated heat flow did affect the basin during its evolution, however, and was associated with igneous activity. The original sedimentary package in the Newark basin was approximately 2.5 km thicker than today. -from Authors
