Airborne electromagnetic data and processing within Leach Lake Basin, Fort Irwin, California
Releases airborne survey data, resistivity cross-sections and depth slices derived from data inversion. Resulting resistivity models confirm geologic framework, constrain hydrostratigraphy and depth to basement, and reveal fault and fold distribution. |
