Detailed Description
Simplified geologic map (left); red lines are geologically young faults and the white line outlines new aeromagnetic data. Aeromagnetic map (right) based on older data; colors show small variations in the Earth's magnetic field that are caused by rocks that contain magnetic minerals, such as magnetite. Arrows point to a linear feature that is not offset by faults (shown in black). New detailed data will allow us to map in more detail how much right-lateral offset is possible on these faults within the white line.
