Faults of Texas, USA - Data Basin
The only comprehensive sources of regional- and national-scale geologic maps are state geologic maps with scales ranging from 1:100,000 to 1:1,000,000. Digital versions of these state maps form the core of what is presented here.
Geophysical surveys (resistivity, natural potential [self-po-tential], conductivity, magnetic, and ground penetrating radar) were conducted at three locations across the Mount Bonnell fault in the Balcones fault zone of central Texas.
