Lincoln County, Geology
USGS's geologic map puts all of Lincoln County's mapped land in one class: low radon potential. The map puts 63.3% of Lincoln County in the area it calls Mississippi Alluvial Plain and 36.7% in West Gulf Coastal Plain. USGS gives the first a radon index of 8 and the second 7, both 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 | 63.3% |
| West Gulf Coastal Plain | Glauconitic, phosphatic, and carbonaceous sediments. | Low | 7 | 36.7% |

Across Arkansas 21.3% of the land is rated moderate; none of Lincoln County's is. None of the 5 counties that border it has any moderate-potential ground either.
