Wilkinson County, Geology
USGS's geologic map puts all of Wilkinson County's mapped land in one class: low radon potential. The map puts 49.3% of Wilkinson County in the area it calls Pine Hills and 35.3% in Loess Hills, with one smaller area beside them. USGS gives the first a radon index of 6 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 |
|---|---|---|---|---|
| Pine Hills | Sand, sandstone, bentonitic clay, quartzite, gravel, tuff, and siltstone. | Low | 6 | 49.3% |
| Loess Hills | Loess. | Low | 7 | 35.3% |
| Mississippi Alluvial Plain | Alluvial sand, silt, gravel, and clay. | Low | 8 | 15.2% |
