Geologic and aeromagnetic maps of northeastern California
By Geology, Minerals, Energy, and Geophysics Science Center
2016 (approx.)
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.

Geologic Mapping in the Southern Pacific Border and Sierras provinces, California
This project uses geologic and geophysical mapping to build an earth-science framework for scientific investigations that include assessments of critical resources, such as groundwater, and of hazards, such as those resulting from earthquakes, in California west of and including the Sierra Nevada and Cascade arc. Questions of particular interest include: What are the geometries, slip rates, and...
