Magnetics and Gravity

	Magnetics Gravtiy

Gravity Surveys are used for the exploration of large scale regional structures and the detection of local variations in density. Large-scale surveys Nation-wide gravity surveys Regional structures Mapping of fault zones Detection and extent of salt domes Exploration of deposits Structures associated with oil and gas Detection of mineral, coal and lignite deposits Engineering and environmental geophysics Detection of voids and effects of subrosion Detection of shallow cavities - from the surface and inside tunnels Detection of waste disposal sites
