Exploration experience gained in specific salt basins of West Africa may not be directly applicable to other salt basins along the entire passive margin. To conduct a comparative structural analysis, regional reflection seismic transects were constructed across the salt basins of Morocco, Senegal, Guinea-Bissau, Equatorial Guinea, Gabon and Angola.
Regional-scale similarities of the salt basins include the progressive complication of salt-related structures basinward, the change from an extensional domain on the shelf to a compressional domain on the slope and the presence of a toe-thrust front at the oceanward edge of the basins. Regional-scale differences are partly attributed to...

Petroleum Geology of Africa: New Themes and Developing Technologies
As frontier exploration in Africa moves into ever-deeper water and new basins, there is an increasing need to mitigate the high costs by reducing risk. One way of doing this is by drawing on knowledge from other areas. The book includes regional papers ranging from syntheses on a continental scale to details of the salt tectonics of the West African margin. It also addresses the need to continue using technologies to their limits by including papers on topics as diverse as gravity interpretation and fluid inclusion studies. The book provides essential reading for those requiring further insight into the origins of Africa’s diverse petroleum systems, and will be key to geologists and geophysicists involved in the exploration for and exploitation of oil and gas throughout Africa. Of particular note is the supplementary CD-ROM containing maps of Africa’s petroleum basins classified by age of target reservoir system.
