Figure F2. Prestack time migration of SCREECH Line 2, which crosses Sites 1276 and 1277 (Shillington et al., 2004). Note the continuity of seismic stratigraphic horizons (e.g., AU1, AU2, and U horizons) over much of the profile. A. Plot of the seaward two-thirds of the SCREECH Line 2. Locations of magnetic anomalies M3 and M0 are after Srivastava et al. (2000) and Shillington et al. (2004). Black box outlines region shown in B and C. B. SCREECH Line 2 covering transitional basement and Site 1276. Few basement features can be observed beneath the strong U reflection and other reflections in the lowermost sedimentary section. C. Same profile as B, with interpretations of the AU1, AU2 (after Tucholke and Sibuet; this volume), and U reflections, indicated with purple, red, and blue dashed lines, respectively.
