  Weaubleau-Osceola structure - Encyclopedia, History, Geography and Biography
It consists of an area of severe structural deformity and extensive brecciation that was poorly understood and had been thought to be the result of either faulting or of a cryptoexplosive event.
These 38th parallel structures are thought to possibly be the result of a serial impact, similar to that of comet Shoemaker-Levy 9 on Jupiter, an extremely unlikely event on Earth.
The Weaubleau-Osceola structure is one of the fifty largest known impact craters on earth and the fourth largest in the United States.

One of the largest meteorite craters in the United States is in the state of Missouri where a rock 1,200 feet in diameter plunged into Earth's atmosphere sometime around 310 to 340 million years ago.
Osceola and Weaubleau are not within the impact crater.
The structure of the ground around the site first was first identified as an impact crater by Dr. Kevin Evans of Southwest Missouri State University.

 Geotimes - July 2003 - Jumbled Missouri geology Linked to Impact
The site, which may be the fifth-largest impact structure in the United States, has attracted attention and support from the local community — from science students to “interested folks from all walks of life,” says researcher Kevin Evans at Southwest Missouri State University.
Charles Rovey, one of the SMSU team members, identified shocked quartz grains in the breccia that overlies the impact structure, suggesting that the jumbled rock may be fallout from the impact.
The structure’s age may correlate to two other Missouri structures, Decaturville and Crooked Creek, that some have proposed are remnants from a string of related impacts; however, age constraints are still rough.

 POST-DEFORMATIONAL REMAGNETIZATION OF THE WEAUBLEAU-OSCEOLA STRUCTURE, SW MISSOURI
The age of the structure is stratigraphically constrained between deposition of the deformed Osagean limestones and the overlying undeformed Pennsylvanian (Desmoinesian) units.
Paleomagnetic samples were collected from the tilted Burlington-Keokuk and Sedalia formations inside the structure, the fall-back breccia, and the undeformed Burlington-Keokuk outcrops from outside of the structure.
It is not clear that the CRM present in the crater is directly related to the impact, as a similar component is found in undeformed limestones outside of the crater.

 Impact crater Summary
An impact crater is a physical scar on a planetary body's surface (topographic depression or geological structure) that is the result of hypervelocity impact by a minor planet, such as an asteroid, comet, or meteorite.
Geologists distinguish an impact crater, which is rather easily seen, from an impact structure, which is an impact crater that may be in a state of poor preservation.
At present, there are about 150 to 200 impact craters and impact structures on Earth that have been scrutinized sufficiently to prove their origin.

 IMPACT ORIGIN OF THE WEAUBLEAU-OSCEOLA STRUCTURE IN SOUTHWESTERN MISSOURI
The circular drainage is a ring moat, and an uplifted outer rim marks the margin of the transient crater with a diameter of approximately 27 km.
Within the circular structure, highly deformed carbonates of the Pierson-Burlington-Keokuk formations undivided (Osagean) are overlain by undeformed polymict carbonate breccia and by younger Pennsylvanian conglomerate (Graydon Formation, Atokan) and sandstone of the Cherokee Group (Desmoinesian).
Exposures of deformed carbonates in 10-25 m high quarry walls near the center of the structure indicate a downward transition from brittle to ductile deformation; three structural domains include heavily fractured and sheared rock overlying tightly folded, thrust-faulted strata, which overlie beds with more open folds.

 OBLIQUE IMPACT AT WEAUBLEAU-OSCEOLA STRUCTURE, MISSOURI
The Weaubeau-Osceola structure is a middle to late Mississippian meteorite impact site.
The unusual geometric configuration of structural elements and local strain fabrics indicate that it was oblique impact from the southwest with an estimated angle of incidence of ~15°-30°.
Literature studies suggest that impacts with incidences >30° tend to form concentrically ringed structures, whereas low-angle impacts (<15°) typically form oval craters.
