This chapter primarily comprises a set of 20 isopach and structure-contour maps of various stratigraphic intervals and horizons in the National Petroleum Reserve in Alaska (NPRA). These maps synthesize all available new information with the old in a format that allows easy integration with geologic studies in nearby areas of the North Slope. They also provide the geologic framework for the evaluation of organic geochemical data in oil and gas source-rock studies. The area mapped is limited to the relatively undisturbed (autochthonous) rocks in the NPRA. The tectonically transported (allochthonous) rocks of the Brooks Range and southern foothills provinces are not included because of differences in stratigraphy, structural complexity, and absence of subsurface information. These maps differ in several important aspects from isopach and structure maps of many of the same intervals and horizons made by Tetra Tech, Inc. The maps in this chapter integrate the surface geology more completely and are drawn at a more generalized regional scale. The structure contours of the Tetra Tech maps, based on seismic data, have been adjusted to coincide with stratigraphic boundaries established in wells. The isopach intervals used here have stratigraphic boundaries, whereas the Tetra Tech maps used boundaries based on seismic reflections (parastratigraphic units).
