Maps of the a observed gravity data, b gravity data calculated from the 3D geologic model with assumed, starting rock unit density values, and c the RMS misfit between the two (i.e., misfit = observed − calculated). The majority of the misfit across the model area is non-zero (i.e., not green) and indicates poor fit (RMS misfit = 2.18 mGal). Units on the color bars are mGal. Locations of gravity measurements are indicated by black dots
