Bathymetry of a Rifted Margin

Becky Dorsey, Jack Loveless, Melissa Lamb, Andrew Goodliffe, Scott Bennett


Investigate the morphology of rifted margins to examine the roles of structural evolution, sedimentation, and physical and chemical evolution of the crust in the rifting process. This lesson can act as an introduction to more detailed examinations of the roles of extension, sedimentation, and obliquity in rifted margins.

Delivery will be primarily through lab exercises and short lecture segments. Lecture segment will be interspersed the key questions that will be used to assess student understanding of key material. Short and long answer questions, which are linked to the learning outcomes, will be used to assess student learning. Rubrics will be designed for each step. The 2 week segment will culminate in a comprehensive exam comprising short and long answer questions
