The ground under Sharkey County
PredictedUSGS's geologic map puts all of Sharkey County's mapped land in one class: low radon potential. All of it lies in the area the map calls Mississippi Alluvial Plain, to which USGS gives a radon index of 8, in the low band (5 to 8).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Mississippi Alluvial Plain | Alluvial sand, silt, gravel, and clay. | Low | 8 | 100% |
