The Boyle Group, also known as the Boyle Limestone or Boyle Dolomite is a geologic group found in Kentucky. It dates back to the Devonian period. The Boyle is bound by two unconformities. The one at the top is the Taghanic unconformity and the one at the bottom is the Wallbridge Unconformity. The New Albany Shale uncomfortably lies on top of the Boyle. At its based the Boyle rests uncomfortably on the Crab Orchard Formation.
