ⓘ Bloyd Formation

The Bloyd Formation conformably overlies the Hale Formation and unconformably underlies the Atoka Formation. Five formal and one informal members are recognized in the Bloyd Formation in stratigraphic order:

  • Baldwin coal an informal unit at the top of the Woolsey Member
  • Dye Shale Member
  • Woolsey Member
  • Kessler Limestone Member
  • Brentwood Limestone Member
  • Parthenon Sandstone Member also known as the "middle Bloyd sandstone"

In the eastern parts of the Ozarks in Arkansas, the Bloyd Formation becomes undifferentiated with the underlying Hale Formation and is called the Witts Springs Formation.
