DescriptionUsing a sequence stratigraphic framework, I have created cross sections, base structure contours, and isopach maps of Miocene New Jersey Coastal Plain sequences from the Kirkwood and Cohansey Formations, which provide insights into their distribution, evolution, and possible source of sediments. I created these maps by correlating gamma logs obtained from the New Jersey Geological and Water Survey, plotted in a grid-like fashion, creating 27 transects of strike and dip, and mapping in python using the depths of each sequence. Nine coreholes serve as anchors for correlations due to their extensive lithological and sequence stratigraphic descriptions: Leg 150X Cape May, Atlantic City, Bass River, and Island Beach, and Leg 174AX Ocean View, Ancora, Double Trouble, Millville, and Cape May Zoo. The Kirkwood Formation is divided into eight sequences: Kw0, Kw1a, Kw1b, Kw1c, Kw2a, Kw2b, Kw2c and Kw3, with the older sequences being more extensive and thicker than younger ones, in the Cape May peninsula and near coastal sites. This is due to more accommodation downdip. The source of sediments was from the northwest, with the major depocenter near Ocean View and a lesser one in Bass River. The Cohansey Formation can be subdivided into six sequences: Kw-Ch1, Kw-Ch2, Ch3, Ch4, Ch5, and Ch6. The first two sequences are a mixture of coarser Cohansey sands and finer sediments more similar to the Kirkwood Formation, and have relatively broad distributions, and are easier to correlate downdip, in the Cape May peninsula, while the younger sequences are more restricted. Sediment supply seems to have come from the from the northwest, into the Cape May peninsula.
