Results are given of surveys conducted in 1944-1946 by the Esso Standard Oil Company in northeastern North Carolina, and extending into the southeast corner of Virginia. Gravitational, magnetic, refraction and reflection surveys were made. The gravity and magnetic maps indicate a basement of complex composition, with a grain approximately north-south. The refraction data show the regional eastward dip of a high velocity layer, which in the western part of the area is identified as crystalline basement, but which in the eastern part is believed to be a limestone in the Lower Cretaceous. The reflection survey of Pamlico Sound shows regional east dip with a number of noses plunging east and northeast, and some possible faults but no closed structures.
