  1. The Granite Wash: A Few Thoughts About The Big Picture G. Randy Keller

  2. The Southern Oklahoma Aulacogen (SOA) is a major tectonic feature of global significance Wichita. Amarillo index The Southern Oklahoma aulacogen

  3. The Late Precambrian Structural Framework

  4. Afar vs. SOA Triple Junctions The scales are approximately the same

  5. SOA experiment index UTD/UTEP Refraction/WAR Experiment AMOCO Research Crew 21 large shots

  6. SOA Velocity Model-Upper Crust

  7. Crustal model derived by integrated analysis of seismic, geologic, and gravity data The mafic core of the Wichita uplift resides almost completely in the upper plate of the Mountain View thrust system

  8. Gravity Anomalies - Amarillo Uplift NS NE

  9. Integrated model for the NE profile (by Diana Smith) North A large mafic core and a nearly vertical fault on the north side of the uplift are required to fit the observed data.

  10. What is the extent of the SOA? SOA Extent

  11. European Tectonics Let’s revisit the classic analogy with the Dniepr-Donets basin

  12. Pripyat-Dniepr-Donets-Basin Devonian rifting Permian reactivation Late Cretaceous inversion The DOBRE Project

  13. DOBRE - Velocity Structure

  14. Major tectonic inversion that involved thrusting and strike-slip created the structures that were the source of the “Granite Wash”. A better understanding of these structures should help our efforts to exploit the “Granite Wash” and perhaps even find new fields.
