Figure 16: 2D geophysical model for profile A-A′ (located in Figures 24, 6, and 15). Observed curves were extracted from the grids for reduced-to-pole aeromagnetic data (Figure 2), isostatic residual gravity (Figure 4), and HGM of the reduced-to-pole aeromagnetic data (HGM of RTP) (Figure 6). MHSF: Mineral Hot Springs fault (revised), SLFZ: San Luis Creek fault zone, VGFZ: Villa Grove fault zone, and VGTF: Villa Grove town fault. Colored arrows point to the locations of inferred faults from Figure 15, coded in a similar fashion: magenta indicates active (younger), red (with black outline) active (older), and purple potentially active.
