Abstract Details

2011, Master of Science (MS), Ohio University, Geological Sciences (Arts and Sciences).
The Flynn Creek impact structure in north-central Tennessee was formed by an extraterrestrial impact ~382 Ma in a shallow sea. Roddy (1979) first suggested that the crater may have formed from an oblique impact citing the asymmetric structure of the central uplift; however, due to the burial of the crater, much of the usual evidence used for determining obliquity is inaccessible. The purpose of this study was to determine if the structural geology of the crater rim can be used to determine obliquity and angle of impact. By utilizing the areas of greatest deformation, coupled with post impact topography, and also strike orientation of the rim strata, it was found that the Flynn Creek crater was formed by an oblique impact following a trajectory from the present day northwest to the southeast, probably at a shallow (5°) angle.
