Figure 173-4. East-west migrated multichannel seismic reflection profile Lusigal-12 through Sites Iberia 8A, Iberia 9A/9B, 900, and 901 (Fig. 1). The lower profile is an interpretation of basement reflections seen in the upper profile. Syn-rift I sediments are marked by close diagonal ruling; syn-rift II sediments are marked by coarser ruling. H is a detachment fault controlling extension during syn-rift I phase; L is a listric fault active during syn-rift II phase. Pre-rift units are probably present in fault block FB, but are not identified. The magnetic anomaly profile (top) was computed from the data set used to produce the magnetic anomaly chart in Fig. 3.
