Jackson County, Geology
Most of the ground under Jackson County is one class on USGS's geologic map: 84.8% of its land is high radon potential, with 14.2% moderate and 1.1% low. The map puts 84.8% of Jackson County in the area it calls Interior Low Plateaus and 14.2% in Appalachian Plateau, with one smaller area beside them. USGS gives the first a radon index of 12, in the high band (12 to 17), and the second 9, in the moderate band (9 to 11).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Interior Low Plateaus | Mississippian carbonate rocks and shales. | High | 12 | 84.8% |
| Appalachian Plateau | Limestone, sandstone, carbonaceous shale, coal | Moderate | 9 | 14.2% |
| Appalachian Plateau | Sandstone and shale. | Low | 8 | 1.1% |
