Gravity and magnetic data were acquired for the area surrounding and including CNRA between the outcrop data and the subsurface data. Analysis of gravity and magnetic data, obtained from 180 data stations in a 125 square kilometer area surrounding, and including, CNRA, is presented. These data are analyzed using a Fast Fourier Transform computer program. Second vertical derivatives are computed and incremental downward continuation of the gravity and magnetic fields is carried out.
Utilizing geologic data from various sources, density model inversion of gravity data was done using a least-squares matrix inversion computer program. North-south observed gravity profiles were used to develop geologically feasible models of the structural geometry for areas of limited geologic data.
Interpretation and synthesis of these data sets resulted in the interpolation of fault locations beneath Pennsylvanian-aged conglomerate.
