Imaging of Fault and Fracture Controls in the Arbuckle-Simpson Aquifer, Southern Oklahoma, USA, through Electrical Resistivity Sounding and Tomography Methods

Figure 1

(a) Geographic location of the study area in Oklahoma. (b) Fault structure map of the Mill Creek block, Arbuckle-Simpson aquifer (From [13]). Line A-B represents the N-S sounding profile. CD and EF represent the electrical resistivity tomography profile locations. Red dots indicate the locations where electrical resistivity sounding data were collected. Faults F1 and F2 are imaged in the subsurface using electrical resistivity method to understand how they control ground water flow in the region. Well locations from which depth to groundwater level were obtained are shown by blue dots along with well numbers. Blue square indicates the location of Pilot Springs.
