A gravity and magnetic study of the Triassic Richmond Basin, Virginia

Abstract

Gravity, aeromagnetic, seismic, drill hole and surface geologic data have been integrated to determine the three dimensional configuration of the Triassic Richmond basin in Virginia. A 2 ½ dimensional generalized linear inversion algorithm was used to model five gravity and six aeromagnetic profiles. The gravity and magnetic models indicate that the structure of the basin is primarily controlled by the western border fault adjacent to the deepest part of this asymmetrical basin. The eastern margin of the basin is a nonconformable contact though locally it is a fault contact. The geophysical data define the intrabasin structure and the presence of diabase dikes.
