The ground under De Baca County
PredictedUSGS's geologic map puts all of De Baca County's mapped land in one class: moderate radon potential. The map puts 73.7% of De Baca County in the area it calls Great Plains Pecos Valley Section and 23.5% in Basin and Range Sacramento Section, with one smaller area beside them. USGS gives the first a radon index of 9 and the second 10, both in the moderate band (9 to 11).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Great Plains Pecos Valley Section | Triassic sandstone, siltstone, mudstone, Quaternary alluvial and eolian sand and silt. | Moderate | 9 | 73.7% |
| Basin and Range Sacramento Section | Paleozoic marine limestones and shales. | Moderate | 10 | 23.5% |
| Ogallala Formation/High Plains | Sandstone, siltstone, minor shale of the Ogallala Formation. | Moderate | 9 | 2.8% |
