DECATURVILLE IMPACT STRUCTURE

by: Charles O’Dale

  • Type: Central peak
  • Age Ma: 260-323 (Geological dating)a
  • Diameter: 5.5 km
  • Location: N 37° 53’ 38″ W 92° 43’ 00″

aThe age of the Decaturville impact structure is not definitely known but is almost certainly post-Pennsylvanian, and may be younger than Cretaceous.
