Comment on this resource
This web page explains the goals and benefits of studying gravity and magnetic data to understand subsurface geology of the Earth. It discusses uses of gravity and magnetic measurements in providing information about the density of rocks, and explains how these measurements are useful in exploration for oil and gas and mineral deposits. The page uses gravity and magnetic maps and as well as figures to illustrate some of the concepts of interpretation, such as amplitude, frequency and anomalies.
