How to get it
Various scale regional gravity and magnetic surveys can be obtained from the following sources:
- Existing surveys (both ground and airborne acquired) from contractors
- Contractor-acquired data along seismic lines during seismic surveys
- Purchased surveys from government sources in the U.S. and overseas
Where to use it
Such data are extremely useful in extensional and rift terranes and as a guide in planning subsequent seismic surveys.
Examples of use
- Nettleton, L., L., 1971, Elementary gravity and magnetics for geologists and seismologists: Society of Exploration Geophysicists Monograph Series 1, 121 p.
