1Construct several laterally consistent balanced x-sections to form the framework for a 3D structural model.
2Build 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)
3Restore the 3D model to answer the following questions:
4Outline 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.
Before arriving: Preread assignments (geology of the IUGFS area, balancing cross sections and 3D modeling software docs)
Day 0: Arrive at IUGFS by 6:00 pm for introductions, safety briefing, course goals and schedule discussion
Day 1: (FS) Hwy 2 map, x-‐section topo profiles, stratigraphy and formation thicknesses, define field teams, define each team’s work assignments, introduction to the software and workflows.
Day 2: (field) Field introduction to the stratigraphic units and reconnaissance of the structural geology
Day 3: (field) Each team collects field data for their first dip x-section and starts building that x-section.
Day 4: (FS) Cross-team agreement on lateral consistency and preliminary balancing the first x-sections
Day 5: (field) Each team collects field data for their second dip x-section and starts building those x-sections, one team also does Jefferson River cut x-section.
Day 6: (FS) Cross-team agreement on lateral consistency of all dip x-sections and near-final balancing of dip x-sections.
Day 7: (FS and field) Build strike x-sections, agree on 3D consistency, field checking to resolve any questions or disputes.
Day 8: (FS) 3D model building.
Day 9: (FS) Finish 3D model building and start 3D reconstruction.
Day 10: (FS) Finish 3D reconstruction, interpret what it means and identify of any pitfalls in the logic.
Day 11: (field) Summarize interpretation results, walk through field area to discuss the interpretation.
Day 12: (FS) Define publication ideas, outline each publication, assign post-course responsibilities, adjourn by 4:00 pm Depart IUGFS either the evening of Day 12 or the following morning.
