The ground under Tishomingo County
PredictedMost of the ground under Tishomingo County is one class on USGS's geologic map: 80.5% of its land is low radon potential, with 16.5% high and 2.9% moderate. The map puts 80.5% of Tishomingo County in the area it calls Tombigbee Hills and 16.5% in Interior Low Plateaus, with one smaller area beside them. USGS gives the first a radon index of 8, in the low band (5 to 8), and the second 12, in the high band (12 to 17).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Tombigbee Hills | Clay, sand, sandstone, chalk, chalky marl, quartzose, chert gravels, and quartz sand. | Low | 8 | 80.5% |
| Interior Low Plateaus | Mississippian carbonate rocks and shales. | High | 12 | 16.5% |
| Pontotoc Ridge/Black Prairies | Glauconitic sand, clay, sandy limestone, micaceous chalk, and lime. | Moderate | 9 | 2.8% |
