The ground under Lowndes County
PredictedUSGS's geologic map splits Lowndes County: 62.5% of its land is low radon potential and 37.5% moderate. The map puts 62.5% of Lowndes County in the area it calls Tombigbee Hills and 37.5% in Pontotoc Ridge/Black Prairies. USGS gives the first a radon index of 8, in the low band (5 to 8), and the second 9, in the moderate band (9 to 11).
| 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 | 62.5% |
| Pontotoc Ridge/Black Prairies | Glauconitic sand, clay, sandy limestone, micaceous chalk, and lime. | Moderate | 9 | 37.5% |
