CELEBRATING 100 YEARS OF THE OKLAHOMA CITY GEOLOGICAL SOCIETY MOLLY TURKO, PhD STRUCTURAL GEOLOGY EXPERT FIELD TRIP "STRUCTURAL GEOLOGY OF THE WICHITA UPLIFT" October 1, 2021 8:00am to 5:00pm REGISTRATION LINK: Dr. Molly Turko has over 13 years of experience in the oil and gas industry and is a subject matter expert in structural geology. She hashad the opportunity to work in multiple basins in the U.S including the Anadarko, Ardmore, Delaware, Powder River, Appalachian, Onshore Gulf Coast, and Rocky Mountain Basins. She received both a B.Sc. (2009) and a M.Sc. (2011) in geology from the University of Tulsa followed by a Ph.D. (2019) from the University of Oklahoma where she studied under Dr. Shankar Mitra. Her work experience includes Chesapeake Energy, Devon, and several small operators in Tulsa. She has taught courses for R.M.A.G., AAPG, Applied Stratigraphix , and for the Ore Geology Conference. She is also the Vice President of AAPG’s Petroleum Structure and Geomechanics Division for 2021 2023. Molly’s passion is mentoring and teaching, but her favorite role is leading structural geology field courses in Nevada and Southern Oklahoma. She is currently a team member of Applied Stratigraphix as their Structural Geology Expert along with consulting for Turko Tectonics and Structural Geology. The Wichita Mountains in southwest Oklahoma are marked by a complex tectonic history filled with debate on the structural styles, evolution, and origin. During the Precambrian-Cambrian breakup of Rodinia, a failed rift tore through southern Oklahoma emplacing a Large Igneous Province. The rift then began to cool and subside as it became filled with sedimentary rocks dominated by thick carbonates. The region was relatively quiet until about the Late Mississippian through Pennsylvanian when the Pennsylvanian Orogeny uplifted the failed rift exposing the Wichita Mountains as seen today. Debates have pursued on the method of uplift, which include arguments for strike-slip, thrusting, and transpression. While much of the original rift geometry was masked by later deformation, it is also important to consider the impact of pre-existing structures on later Pennsylvanian deformation,
