Figure 7. Part of migrated line LG12 and unmigrated line GP20 (from Groupe Galice, 1979, their fig. 9A, which does not show shotpoints or horizontal scale) to show how seismic units defined in this study correlate with those identified in the area of Site 398. Note the correlation between the interval of inclined reflectors on GP20 with the base of our Unit 3 and that between the base of our Unit 4 and Unit 2 of Groupe Galice. For reasons explained in the text, we consider that Groupe Galice failed to recognize their Unit 4 on this part of line GP20. We believe that the top of this unit occurs at 830 ms on the left side of the extract shown and correlates with the boundary between our Units 5 and 6.
