The ground under Briscoe County
PredictedUSGS's geologic map splits Briscoe County: 59.1% of its land is low radon potential and 40.9% moderate. The map puts 59.1% of Briscoe County in the area it calls Central Texas and 40.9% in Northern High Plains and Plateaus. USGS gives the first a radon index of 7, in the low band (5 to 8), and the second 10, in the moderate band (9 to 11).
| 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 | 59.1% |
| Northern High Plains and Plateaus | Tertiary sandstone, siltstone, shale. | Moderate | 10 | 40.9% |
