Aeromagnetic surveys of Nevada, merged to form seamless grids across the state. Gravity anomaly data are provided as well. Data provided in a variety of formats.
A simplified geologic map, raw gravity and magnetic data, with derivative products including depth-to-source and rock densities, with limited interpretations of the underlying geology, structures, and mineral resources.
Best available public-domain aeromagnetic and gravity data in the State of Michigan merged into composite grids. Magnetic data compiled from 25 separate magnetic surveys.
The long-wavelength (50-2,500 km) content of the regional magnetic anomaly compilation was improved by utilizing a nearly homogeneous a nearly homogeneous set of NURE magnetic surveys flown from 1975 to 1981
Airborne measurement of the earth's magnetic field over all of North America provides gridded data describing the magnetic anomaly caused by variations in earth materials and structure.
