Divergent Margins and Rift Basins

Estimated Time to Complete:

3 hours 20 minutes

(average of 20 minutes per Subtopic)

Applies tectonic concepts learned in GL601 and 602, focusing on petroleum habitats in divergent margin and rift basins. Discusses theories of rifting and its effect on sedimentation. Classifies rift basins and examines each type through present day examples.
