Existing geological and geophysical information shows that the physiographic components of continental margins (continental shelves, continental slopes, and continental rises) in different regions have characteristics that depend upon their tectonic and sedimentary histories. These characteristics also determine whether significant oil and gas accumulations probably are present, may be present, or probably are absent. Most promising are the oil and gas prospects of divergent continental margins whose sediment accumulations are large and less disturbed than those of convergent margins; translation margins are intermediate. Better knowledge of all continental margins, particularly in their middle parts, awaits exploration by deep drilling. Without such information estimates of the Earth's total oil and gas resources must remain very incomplete.
