United States
| Location | Lee County and Chatham County, North Carolina. |
| Area | 59,000 acres |
| Thickness | 800 feet |
| Formation Details | The Cumnock Formation is located in Triassic strata of the Sanford sub-basin of the Deep River Basin. |
| Notes | Organic geochemistry and thermal maturation analyses indicate that the black shale in the Cumnock Formation is gas-prone, and that values of total organic carbon (TOC) exceed 1.4 percent in places. The Cumnock Formation contains systematic fracture sets that are observable in outcrop, on 1:24,000-scale geologic maps superimposed on LiDAR data, and possibly in drill cores. |
