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.
Figures & Tables
Written in 1977 the publication presents interpretations of then-new data bearing on the geology and geophysics of continental margins. The book includes a discussion of plate tectonics and evolution of continental margins; presentations on the stratigraphy and structure of pull-apart and compressional margin;, prospective petroleum source rocks, their organic content, rate of burial, and distribution on slopes and rises of different margin types; prospective reservoir rock patterns in relation to depositional processes and to the sedimentary and structural histories for different types of continental margins; and seismic recognition of depositional facies on slopes and rises for different margin types with varying rates of sediment supply during eustatic sea-level changes.
