Rankin County, Geology
The ground under Rankin County
PredictedUSGS's geologic map puts all of Rankin County's mapped land in one class: low radon potential. The map puts 64.3% of Rankin County in the area it calls Jackson Prairies and 34.4% in Pine Hills, with one smaller area beside them. USGS gives the first a radon index of 8 and the second 6, both in the low band (5 to 8).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Jackson Prairies | Sand, marl, clay, and limestone. | Low | 8 | 64.3% |
| Pine Hills | Sand, sandstone, bentonitic clay, quartzite, gravel, tuff, and siltstone. | Low | 6 | 34.4% |
| North Central Hills/Flatwoods | Tertiary nonmarine to deltaic sediments ranging from sand to clay. | Low | 8 | 1.3% |

Rankin County beside the ground around it
Across Mississippi 0.1% of the land is rated high; none of Rankin County's is. None of the 6 counties that border it has any moderate-potential ground either.
