The ground under Cottle County
PredictedUSGS's geologic map puts all of Cottle County's mapped land in one class: low radon potential. All of it lies in the area the map calls Central Texas, to which USGS gives a radon index of 7, in the low band (5 to 8).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Central Texas | Cretaceous through Quaternary marine sandstone, shale, chalk, limestone, siltstone, clay, and lignite. | Low | 7 | 100% |
