Figure F3. Industry multichannel seismic reflection line passing 5.5 km east of Site 1258. See Figure F1 in Shipboard Scientific Party ("Site Survey and Underway Geophysics"), this volume, for a location map for this line. The site location is projected onto the line at the point of closest passing. Note the coherent nature of seismic Unit 2 to the right of the figure, which terminates abruptly at the upper red dashed line then becomes incoherent in the central portion of the figure. Unit 3 is represented by the two reflection cycles above the Horizon C and is barely resolved with this seismic system. The sediment package underlying Horizon C is part of the synrift sequence and is heavily faulted and folded.
