Course Description

Construct several laterally consistent balanced x-sections to form the framework for a 3D structural model.
Build a 3D structural model in 3DMove that incorporates the surface geology, subsurface geology and relevant geology that has been eroded (the model will include the Mississippian – Upper Cretaceous).
Restore the 3D model to answer the following questions
- What is the composite slip direction that explains the deformation? Can we define the minimum magnitude of the slip vector?
- Can all the deformation be explained with a single deformational event or does it require multiple events? If multiple events are needed, what are their slip directions and minimum vector magnitudes?
- Given the 3D geometries (e.g., shape of the 3D fault surfaces), how much northward dip post-dates the emplacement of the thrust sheets exposed in the study area?
Outline at least one publication that will be written from the study and define post-seminar responsibilities for the publication(s).
Each student will balance at least one x-section, build a 3D model and restore the 3D model.

Western hanging wall and footwall ramps with Je syncline in the main thrust horse.
Hangingwall, “mystery hill” in the main thrust horse and the southern thrust sheets.
Hangingwall, the east fault cut-off of the main thrust horse and eastern exposure of the southern thrust sheets.
East Pp limb of J and footwall cutoff of Kkg.
West flank of Kk syncline, east side of Jm fishtail and very low angle footwall ramp.
East end of Kk syncline, Kc footwall cutoff, full thickness of Kk in footwall.
Jefferson River cut x-section.
W-E line through center of Pp J and both flanks of Kk syncline. Mostly done in classroom from map and x-sections 1-6; some field checking.
W-E line along main fault outcrop (down-plunge projection of map). Mostly done in classroom from map and x-sections 1-6; some field checking.
