Introduction:

The gravity methods measure spatial variations in the Earths gravity ?elds. Changes in gravity field are caused by variations in rock density. Gravity measurements are used for regional and prospect-scale mapping. The gravity method was the ?rst geophysical technique to be used in oil and gas exploration. In oil exploration, it is particularly applicable in salt provinces, overthrust and foothills belts, underexplored basins, and targets of interest that underlie high-velocity zones. In mining applications gravity method is used frequently to map subsurface geology and to directly calculate ore reserves for some massive sul?de orebodies. The development of airborne gravity systems (known as aerogravity) with precision suitable for mineral targeting, provided the possibility of aerogravity in mineral exploration. Recent moving-platform gravity gradiometers have become available and promise to play an important role in future exploration. The gravity and magnetic methods have much in common, but they also have important aspects of data acquisition and reduction.
