Latimer County, Geology
The ground under Latimer County
PredictedUSGS's geologic map puts all of Latimer County's mapped land in one class: low radon potential. The map puts 58.4% of Latimer County in the area it calls Ouachita Mountains and 29.2% in Lower Arkansas River Valley, with one smaller area beside them. USGS gives both 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 |
|---|---|---|---|---|
| Ouachita Mountains | Mississippian and Pennsylvanian limestone, sandstone, siltstone, shale, conglomerate. | Low | 8 | 58.4% |
| Lower Arkansas River Valley | Pennsylvanian sandstone, siltstone, shale. | Low | 8 | 29.2% |
| Central Oklahoma Plains and Hills | Nonmarine Permian and Tertiary rocks, including shale, sandstone, and conglomerate in the western part, and Mississippian and Pennsylvanian rocks in the eastern part. | Low | 7 | 12.4% |
