—Structural cross sections and restorations from Salin subbasin. Cross sections were originally drawn at approximately 1:84,000 scale and are based on two-dimensional seismic data, well data, surface geology, and aeromagnetic data (for depth-to-basement values). Small errors in restorations are attributed to our attempts to honor seismic data. Because the geometry of the termination of stratigraphic units west of the western outcrops is not known, and because lower Tertiary units are not present across the entire basin, local pin points were used (Woodward et al., 1985). Deformation is thought to have begun in the Miocene, thus only pre-Miocene bed lengths were measured. Locations of cross sections are shown on Figure 2. Abbreviations for stratigraphic units are defined on Figure 3. (A) Cross section AA′ showing western outcrops, Yenangyat-Chauk thrust, and Gwegyo thrust. The unconformity on the hanging wall of the Yenangyat-Chauk thrust is projected from the south. (B) Cross section BB′ showing western outcrops, Mann fault, and Yedwet uplift. Intraformational Irrawaddy unconformity based on surface geology. Miocene section thickens on the east side of Yedwet uplift. (C) North-south–oriented cross section CC′ showing abundant east-striking normal faults. The Miocene Obogon Formation (shaded) thickens over what is now a positive structural feature, but was originally a basin created by normal faulting, suggesting an inversion of structural fabrics after the Miocene.

—Depth-to-magnetic-basement map of Salin subbasin based on newly acquired aeromagnetic data. Patterns indicate east-northeast–trending uplifts possibly related to normal faults identified on seismic lines (see Figure 4C), or are related to the Mount Popa volcanic trend, which also may be related to the normal faults. Solid lines are locations of structural cross sections (Figure 4), and dashed lines are locations of surface exposures of the major faults and axes of uplifts in the basin (Figure 2). Coincidence between high-relief areas in the basement and the location of faults suggests that fault locations were controlled by the geometry of the basement. Because of the presence of volcanics at the surface and the extreme depth of the basin with respect to its width, there may be considerable error (~20%) in the absolute depths shown here. We believe, however, that the general shape of the contours reflects the basement surface.

—Stereonets (lower hemisphere, equal-angle projections) of structural data from Salin subbasin showing orientation of measured thrust and cross faults. Heavy arcs represent fault planes, shaded arcs represent fracture planes, and dashed arcs represent bedding planes. Fracture patterns associated with thrust faults indicate compressional strain. Most cross faults show a highly oblique sense of slip. Stereonets of reverse and cross faults compare relative orientation of these features. See Figure 5 for thrust fault locations, and Figure 2 and 9 for cross fault locations.
